In the following questions a statement of assertion (A) is followed by a statement of reason ( R).
A : The addition of two vectors `vecP ` and `vecQ` is commutative
R: By triangle law of vector addition we can prove `vecP+vecQ=vecQ+vecP` .

A

If both Assertion & Reason are true and the reason is the correct explanation of the assertion then mark (1) .

B

If both Assertion & Reason are true but the reason is not the correct explanation of the assertion then mark (2)

C

If Assertion is true statement but Reason is false then mark (3).

D

If both Assertion and Reason are false statements then mark (4) .
