Question

Given below are two statements, one is labelled as Assertion (A) and the other one labelled as Reason (R).
Assertion (A): Smart materials can be used as microsensors and microactuators, both.
Reason (R): Smart materials belong to intelligent mechanisms.
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:

Smart materials can act as sensors and actuators because of their unique properties such as shape memory or piezoelectric effects

Answer 1

The Correct Option is B

Smart materials operate as both microsensors and microactuators due to their ability to alter properties in response to stimuli. However, stating that smart materials are inherently intelligent mechanisms does not correctly explain their role as microsensors and microactuators. Smart materials are not necessarily intelligent mechanisms themselves, though they can be components used to create such mechanisms.
