A Correct answer
Explanation

Statement I gives S = 2x (son's age x). Statement III gives (S+4)/(x+4) = 24/13, which with I becomes (2x+4)/(x+4) = 24/13, solvable for x. Statement II (Suchitra:mother = 2:3) is irrelevant to finding Suchitra's age alone. Only II can be dispensed with. The claimed answer A (Only II) is correct.
