Assersion : Out of three meansurements `l = 0.7 m, l = 0.70m` and `l = 0.700m` the last one is most accurate.
Reason: In every meansurements only the last significant digit is not accurately known.

A

If both assertion and reason are true and the reason is the correct explanation of the assertion.

B

If both assertion and reason are true but reason is not the correct explanation of the assertion

C

If assertion is true but reason is false.

D

If the assertion and reason both are false

Text Solution

Verified by Experts

The correct Answer is:
