Answer:

(b) They repel each other.

Step-by-step explanation:

We are given that three objects A, B and C .

Object A and B are  attract to each other and object C and object A attract to each other.

We have to find the true statement about object B and  C.

Let A positive and B is negative.

Therefore, A and B are attract to each other.

When A and C are attract to each other it means C is also negative.

Therefore, B and C are negative.

We know that

Like charges repel  to each other and unlike charges attract to each other.

B and C  repel to each other because they have like charges.

Option (b) is true.
