C Correct answer
Explanation

Total age increase for 16 persons = 16 × 4 = 64 years. Two women aged 12 and 18 are replaced, so their combined age = 30 years. Combined age of 2 men = 30 + 64 = 94 years. Average age of 2 men = 94/2 = 47 years. Option B (46) and D (49) are common arithmetic errors from incorrect addition or division.
