Answer: Carbon
CCS (Carbon Capture and Storage) captures CO2 from power plants/industries, transports it, and stores underground or uses in products (concrete, fuels). Critical for decarbonizing hard-to-abate sectors. India is developing CCS roadmap as part of net-zero strategy. Emerging topic for environment and technology exams.
The Linux command to list all files including hidden ones is ls ________.
- Stratified
- Telecommunication / ITU
- Continuous
- -a
Answer: -a
ls -a lists all files including hidden ones (starting with .). ls -l shows detailed list; ls -h makes sizes human-readable; ls -la combines both. Hidden files store configuration data. Understanding command-line flags is fundamental for Linux administration questions in technical exams.
The CSS box model consists of content, padding, border, and ________.
- margin
- Rain
- Randomized
- Ka
Answer: margin
CSS Box Model: content (actual text/image) → padding (space inside border) → border (edge around padding) → margin (space outside border). Understanding this model is crucial for layout design and responsive web development. Frequently tested in web technology sections of technical exams.
The minimum number of nodes in a binary tree of height h is ________.
- h+1
- qXR / CAD4TB
- Platform
- Parameter
Answer: h+1
Minimum nodes occur in a skewed tree (each node has only one child): height h has h+1 nodes. Maximum nodes in a perfect binary tree of height h is 2^(h+1)-1. Understanding tree properties is essential for algorithm analysis questions in technical government exams.
The Indian law that specifically addresses protection of personal data is called the ________ Act 2023.
- Digital Personal Data Protection
- Horizontal
- AI-based / Machine Learning
- Smart / V2G
Answer: Digital Personal Data Protection
DPDP Act 2023 establishes framework for processing digital personal data, defining rights of data principals and obligations of data fiduciaries. Replaces Section 43A of IT Act 2000. Aligns with global standards while addressing India-specific needs. Critical for compliance questions in banking and UPSC exams.
The Indian government scheme promoting electric vehicle adoption through subsidies is called ________.
- FAME
- UNIQUE
- DID
- CERT
Answer: FAME
FAME (Faster Adoption and Manufacturing of Electric Vehicles) India scheme provides demand incentives for EVs and charging infrastructure.

The frequency at which a crystal oscillator resonates is determined by its physical ________ and cut.
- Kubernetes
- dimensions
- OECD / UNESCO
- Indigenization / Self-Reliance
Answer: dimensions
Crystal oscillators use piezoelectric quartz crystals whose resonant frequency depends on physical dimensions (thickness, shape) and crystal cut (AT, BT, SC).

The time complexity of accessing an element in an array by index is ________.
- UPI
- DHCP
- CERT
- O(1)
Answer: O(1)
Array access by index is O(1) constant time because memory address is calculated directly: base_address + index * element_size. No traversal needed. Contrasts with linked lists (O(n) for access). This efficiency makes arrays ideal for random access patterns, but insertion/deletion in middle is O(n) due to element shifting.
