An attractive electric force occurs between objects with opposite charges. Let's analyze the pairs:

  • Pair A: Object 1 has a charge of -2 and Object 2 has a charge of -1 (both negative). This will not create an attractive force.
  • Pair B: Object 1 has a charge of -3 (negative) and Object 2 has a charge of +1 (positive). This will create an attractive force.
  • Pair C: Object 1 has a charge of +3 and Object 2 has a charge of +1 (both positive). This will not create an attractive force.
  • Pair D: Object 1 has a charge of +1 and Object 2 has a charge of +2 (both positive). This will not create an attractive force.

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

So the correct answer is Pair B.
