Question
The image consists of a chemical reaction involving two structures and a list of options to consider.

On the left, there is a ketone structure with the molecular formula representing a 2-pentanone, involving a carbonyl group (C=O) attached to a five-carbon chain. 

In the middle, there is an arrow with a question mark, indicating an unknown reaction process.

On the right, a linear structure is shown, representing a hydrocarbon chain, specifically pentane.

Below the reaction scheme, there are five options indicated by circles with letters:

- A
- B
- C
- F
- G

These options likely refer to possible reagents or conditions that could result in the depicted transformation from a ketone to an alkane. The task is to select the correct option that facilitates this transformation.

**Question:**

Which of the following reagents are appropriate for the transformation below?

A) PCC  
B) \( \text{Ph}_3\text{P}=\text{CHCH}_3 \)  
C) \( \text{H}_2\text{NNH}_2 / \text{KOH} \)  
D) \( \text{HOCH}_2\text{CH}_2\text{OH} / \text{H}^+ \)  
E) \( \text{CH}_3\text{CH}_2\text{MgBr} \)  
F) \( \text{NaBH}_4 \)  
G) \( \text{LiAlH}_4 \)  

**Transformation Diagram:**

The diagram shows a structural transformation. On the left, there is a ketone with a five-carbon skeleton, specifically 2-pentanone. An arrow indicates the transformation. On the right side, there is a linear structure representing pentane, a five-carbon alkane. The question marks above the arrow suggest the need to identify a suitable reagent to achieve this transformation from a ketone to an alkane.
