2 my friend has blonde black   A, hair      B, shoulder      C , foot         D  arm

The correct answer is A, hair.

Explanation:

In English, "blonde" is a hair color, typically referring to light shades of yellow or gold. "Black" also describes hair color, which is the darkest shade. When someone says "blonde black," they are most likely referring to a person's hair color, where "blonde" could indicate that the hair has been dyed blonde or naturally has blonde highlights, while "black" describes the natural or underlying hair color.

- Shoulder (B): This is part of the body where hair can rest but doesn't describe hair color.
- Foot (C): This is not associated with hair color in any common usage.
- Arm (D): Similar to shoulder, it's a body part but not relevant to hair color.

Therefore, the only logical choice where "blonde black" would make sense is when describing hair.
