The correct answer is: B. in poor health.

• C. ill: This is a possibility, but it is not the only possibility. Someone who looks run down may be tired or unwell, but they may not be ill.
• D. depressed: This is also a possibility, but it is not the only possibility. Someone who looks run down may be tired or unwell, but they may not be depressed.

The phrase “you look a bit run down” suggests that the person is tired or unwell. This could be due to a number of factors, such as lack of sleep, illness, or stress. If you are concerned about someone who looks run down, it is always best to ask them how they are feeling and offer your support.
