Given below are two statements: one is labelled as Assertion A and the other is labelled as Reason R.
Assertion A: Let vector a = (x, y, z) and vector b = (2, 3. 5).
Then a = b if and only if x = 2, y = 3 and z = 5.
Reason R: Two vectors are equal if all their corresponding components are equal.
In the light of the above statements, choose the most appropriate answer from the options given below:
