Assertion & Reason +4 −1

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

Assertion (A) : Optical biosensors offer advantages in terms of real-time monitoring and multiplexing capabilities

Reason (R) : Optical biosensors utilize light-matter interactions to detect analytes, allowing for label-free and non-destructive detection of multiple analytes simultaneously.

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

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