Answer 1

When a positively charged rod touches a neutral metal sphere, the correct response is:

**D. Electrons move from the sphere to the rod through conduction.**

Here's why:

- The positively charged rod has a deficiency of electrons. When it touches the neutral sphere, electrons from the sphere will flow into the rod to balance the charge difference.
- This flow of electrons occurs through conduction, which involves direct contact between the two objects.
- After the contact, the sphere will acquire a net positive charge since it lost some of its electrons to the positively charged rod.
