If an object made of substance A is rubbed with an object made of substance B, then A becomes positively charged and B becomes negatively charged. If however, an object made of substance C, then A becomes negatively charged, What will happen if an object made of substance B is rubbed against an object made of substance C?
(a) B becomes positively charged and C becomes positively
(b) B becomes positively charged and C becomes negatively charged.
(c ) B becones negatively charged and C becomes positively charged.
(d) B becomes negatively charged and C becomes negatively charged.

Explanation

To solve the problem, we need to analyze the charging behavior of substances A, B, and C based on the information given in the question.

### Step-by-Step Solution:

1. **Understanding the First Interaction (A and B):**
- When substance A is rubbed with substance B, A becomes positively charged, and B becomes negatively charged.
- This indicates that electrons are transferred from B to A. Therefore, A has a higher tendency to gain electrons, while B has a higher tendency to lose electrons.
