Answer 1

Hi,
The answer should be letter C.

Answer 2

Answer: The correct option is C.

Step-by-step explanation:

Oxidation reactions are a type of chemical reactions in which a substance looses electrons and forms positive charge. The substance undergoing this reaction is being oxidized.

`A\rightarrow A^++e^-`

Reduction reactions are a type of chemical reactions in which a substance gains electrons and forms negative charge. The substance undergoing this reaction is being reduced.

`A^++e^-\rightarrow A`

For the half reaction in which iron gains electrons means that iron is getting reduced.

Hence, the correct option is C.
