(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.
(e) If assertion is false but reason is true.
Assertion: Out of three measurements \( l=0.7 \mathrm{~m} \); \( l=0.70 \mathrm{~m} \) and \( l=0.700 \mathrm{~m} \), the last one is most accurate.

Reason: In every measurement, only the last significant digit is not accurately known.
