What happens when we bring a positively charged rod close to an uncharged conductor? 

It is electrically neutral.

The correct answer is Option 3: It is electrically neutral.

When a positively charged rod is brought near an uncharged conductor, the conductor undergoes electrostatic induction:

• Free electrons inside the conductor rearrange — they are attracted toward the side near the rod, making that side negatively charged, and leaving the far side positively charged.

• No net charge is transferred — the total charge on the conductor remains zero.

• The conductor is now polarized, not charged.

However, unless the conductor is grounded (allowing charge to flow in or out), it does not acquire any net charge.
