**Question:**

What is the major product of the following reaction?

![Chemical Reaction](https://...)

The reaction involves a ketone with an ethyl group and is treated with sodium borohydride (NaBH₄) in ethanol (EtOH).

**Reactants:**  
- Starting compound: Cyclohexanone structure with an ethyl ester group.

**Reaction Conditions:**  
- NaBH₄ (Sodium borohydride)
- EtOH (Ethanol)

**Possible Products:**

a.) A cyclohexanone with an ethyl group attached to the ester.

b.) A cyclohexanone with an ethyl ester converted to an alcohol group.

c.) A cyclohexanol with the ethyl ester reduced to an alcohol while retaining the carbonyl group.

d.) A diol product where both carbonyl groups are reduced to alcohols.

**Explanation:**

This is a typical nucleophilic addition reaction where sodium borohydride serves as a reducing agent, primarily targeting carbonyl groups to convert them into alcohols. The major product is expected to be where the ketone is reduced to an alcohol, while the ester group remains reactive.
