Question

Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R). Assertion (A): Flip flops are used in counters and registers.
Reason (R): Flip flops are combinational circuits that store data temporarily. In the light of the above statements, choose the most appropriate answer from the options given below:

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

Hint:

Flip-flops are sequential circuits, not combinational.

Answer 1

The Correct Option is C

Concept: Flip-flops are fundamental memory elements in digital electronics.

Step 1: Analyze Assertion (A).
• Flip-flops are used to build:
• Counters
• Registers
• Hence, Assertion is correct ✔

Step 2: Analyze Reason (R).
• Flip-flops are sequential circuits, not combinational
• They store data using feedback Hence, Reason is incorrect ✘

Step 3: Conclusion. \[ \boxed{(3)\ (A)\ \text{is correct but (R) is not correct}} \]
