**Title:** Predicting the Product of a Chemical Reaction

**Question:**
Predict the product of the following reaction:

**Chemical Reaction:**  
The structure depicted includes a five-carbon chain with a ketone group on the second and third carbons, and a hydroxy group on the fourth carbon. This compound is treated with sodium borohydride (NaBH₄) in ethanol.

**Options:**

- **A:** 1,3-pentanediol
- **B:** 3-hydroxypentanone
- **C:** 4,5-pentanediol
- **D:** 1-pentanol

**Explanation of the Reaction Components:**

- **NaBH₄ (Sodium Borohydride):** A common reducing agent used to reduce ketones and aldehydes to alcohols.
- **Ethanol:** Often used as a solvent in reduction reactions.

Given the structure and reagents, predict which product will form when this reaction proceeds. Consider the reducing properties of NaBH₄ and the functional groups present in the starting material when selecting an answer.
