Final answer:

If the charge is increased to +20 nC, there would be 20 electric-field lines coming out of it.

Answer:

If five electric-field lines come out of a +5 nC charge, it means that each line represents 1 nC of charge. Therefore, if the charge is increased to +20 nC, there would be 20 electric-field lines coming out of it. So, the correct answer is d. 20 field lines.
