B Correct answer
Explanation

From statement I, Mohan is 21 years (ratio 7:8 with Ram, difference 3 years gives 8x-7x=3, x=3). From statement II, Mohan is 28 years (average of 30 means sum is 60, John is 4 years older, so m+m+4=60, m=28). Since 21 < 28, statement I gives a smaller value than statement II.
