B Correct answer
Explanation

Let w be wickets before the new match. Total runs conceded = 14w. After 4 wickets for 72 runs, new average = 14.2 = (14w + 72)/(w + 4). Cross-multiplying: 14.2(w + 4) = 14w + 72. This gives 14.2w + 56.8 = 14w + 72, so 0.2w = 15.2, and w = 76. Total wickets = 76 + 4 = 80.
