View correct answer and explanation
Correct answer: B
Correct Option: B
Explanation: Drone swarms coordinate through inter-drone communications and can be disrupted by navigation deception; there is no universal terahertz-link requirement.
Statement-wise Analysis:
Statement 1: Incorrect - Swarms do not inherently use terahertz frequencies to reach a command centre; links vary widely.
Statement 2: Correct - Drones in coordinated swarms may exchange position and task information with one another.
Statement 3: Correct - GPS spoofing can mislead a GPS-dependent swarm and is one possible countermeasure, though efficacy varies.
Option-wise Analysis:
A: Incorrect - Includes unsupported item(s) 1 and omits supported item(s) 2, 3.
B: Correct - This option includes the supported item(s) and excludes the unsupported ones.
C: Incorrect - Includes unsupported item(s) 1 and omits supported item(s) 3.
D: Incorrect - Includes unsupported item(s) 1.
