### Question:
Which of the following compounds is much better monohalogenated in the presence of light with N-bromosuccinimide (NBS) rather than elemental bromine (Br₂)?

### Answer Choices:
(A)![A](/path/to/image_a.png)
(B)![B](/path/to/image_b.png)
(C)![C](/path/to/image_c.png)
(D)![D](/path/to/image_d.png)

### Details of the Structures:
- **Option (A)**: The compound is a hexagon with one double bond, indicating it is a cyclohexene.
- **Option (B)**: The compound is CH₄, which is methane.
- **Option (C)**: The compound shows isobutane structure.
- **Option (D)**: The compound is a cyclopentane, a pentagon structure.

### Explanation:
N-bromosuccinimide (NBS) is commonly used for brominating compounds at allylic positions (adjacent to double bonds) in the presence of light. Elemental bromine (Br₂) can also be used for bromination but is less selective. Therefore, the choice involves understanding the specific conditions where NBS is more efficient.

#### Graphs or Diagrams:
Currently, there are no graphs or diagrams provided other than the structural representations of the compounds. 

### Correct Choice:
The compound given in **Option (A)**, cyclohexene, is more likely to be monohalogenated with NBS under the given conditions due to the presence of a double bond that favors allylic bromination.
