The probabilities of solving a problem by students \( A, B \) and \( C \) independently are \( \frac{1}{2}, \frac{1}{3} \), and \( \frac{1}{4} \) respectively. If they start solving the given problem. independently, then the probability that atleast two of them will solve the problem successfully, is equal to
(A) \( \frac{5}{24} \)
(B) \( \frac{9}{24} \)
(C) \( \frac{7}{24} \)
(D) \( \frac{11}{24} \)
