The attractive electric force occurs between opposite charges.

Let's evaluate each pair of objects:

Pair A: Both charges are negative (-2 and -1).
- Type of force: Repulsive
Pair B: One charge is negative (-3) and the other is positive (+1).
- Type of force: Attractive
Pair C: Both charges are positive (+3 and +1).
- Type of force: Repulsive
Pair D: Both charges are positive (+1 and +2).
- Type of force: Repulsive

The only pair that has an attractive electric force is Pair B.
