Final Answer :
D
Explanation :
According to the principle of conservation of charge, the total current entering a junction must equal the total current leaving the junction. Therefore, if 5 A and 12 A are entering or leaving, the third wire must carry either the sum (17 A) if it's leaving alone or the difference (7 A) if it's entering against the other two.
