Assertion: Zn(s) + CuSO4(aq) → ZnSO4(aq) + Cu(s) Zinc (Zn) is a reductant but itself gets oxidized.

Reason: In a redox reaction, the oxidant is reduced by accepting electrons, and the reductant is oxidized by losing electrons.

A) Both assertion and reason are correct, and the reason is the correct explanation for the assertion.
B) Both assertion and reason are correct, but the reason is not the correct explanation for the assertion.
C) Assertion is correct, but the reason is incorrect.
D) Both assertion and reason are incorrect.

The assertion correctly states that Zn is a reductant and it itself gets oxidized.

Reason: In a redox reaction, oxidant is reduced by accepting electrons and reductant is oxidised by losing electrons.

This is a correct general statement about redox reactions:

The oxidant (oxidizing agent) is reduced by accepting electrons.
The reductant (reducing agent) is oxidized by losing electrons.
Since the assertion is true (Zn is a reductant and gets oxidized) and the reason is a correct explanation of redox reactions, and since the reason directly explains why Zn, as a reductant, gets oxidized:

The correct answer is:
A) Both assertion and reason are correct and reason is the correct explanation for assertion.
