To solve this problem, let's analyze the information given about the objects and their interactions:

1. Object A is negatively charged.
2. Objects B and C both attract A.
3. Objects B and C repel each other.

Now, let’s break it down step-by-step:

### Step 1: Analyze the Interaction Between A and B, and A and C
- Since A is negatively charged:
- If B attracts A, then B must have the opposite charge (positively charged) because opposite charges attract.
- Similarly, if C attracts A, then C must also have the opposite charge of A (positively charged).

At this point, we suspect both B and C could be positively charged because they attract the negatively charged A.

### Step 2: Analyze the Interaction Between B and C
- According to the problem, B and C repel each other.
- Like charges repel each other.

Thus, if B and C repel each other, they must have the same type of charge.

### Conclusion
From the analysis:
- B attracts A (negatively charged), so B must be positively charged.
- C attracts A (negatively charged), so C must also be positively charged.
- B and C repel each other, confirming they have the same charge.

Hence, both B and C are positively charged.

### Correct Answer:
- OA Both B and C are positively charged.
