Question

Assertion: Order of reaction can never be fractional for an elementary reaction.
Reason: An elementary reaction takes place by one step mechanism.
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 the reason is not the correct explanation of the assertion.
C. If assertion is true but reason is false.
D. If assertion is false but reason is true.
