Correct answer: B
Let x be the number of matches played before today's match.
Total runs before today = 38 × x.
After scoring 78, total runs = 38x + 78 and total matches = x + 1.
New average = (38x + 78) ÷ (x + 1) = 42.
Solve: 38x + 78 = 42(x + 1) → 38x + 78 = 42x + 42 → 36 = 4x → x = 9.
Answer: He has played 9 matches this season (before today's match).
