Question

Given below are two statements, one is labelled as Assertion (A) and other one labelled as Reason (R)

Assertion (A) : Operational microwave remote sensing has both active and passive sensors.
Reason (R) : Active microwave remote sensing depends on the emission characteristics of various target surfaces or the media of interest.

In light of the above statements, choose the correct answer from the options given below.

• A. Both (A) and (R) are true and (R) is the correct explanation of (A).
• B. Both (A) and (R) are true but (R) is NOT the correct explanation of (A).
• C. (A) is true but (R) is false.
• D. (A) is false but (R) is true.

Hint:

Always associate active systems with self-generated energy (like RADAR or LIDAR).
They control their own signals and are independent of natural thermal emissions or solar illumination.

Answer 1

The Correct Option is C
