Correct answer: C
(A) Average of first 50 natural numbers = (1 + 50) / 2 = 25.5, matching (III).
(B) Average of odd numbers up to 100 = (1 + 99) / 2 = 50, matching (IV).
(C) Mean of squares 1² to 7² = (1+4+9+16+25+36+49)/7 = 140/7 = 20, matching (I).
(D) Primes between 30 and 50 are 31, 37, 41, 43, 47. Average = 199/5 = 39.8, matching (II).
