9 Strings \( A \) and \( B \) have the same masses and lengths, but string B is under greater tension than string A . Which of the situation(s) is there a possibility that strings A and B are oscillating at the same frequency?
A (1) only
(B) (3) only
C (1) \& (2) only
D (2) \& (3) only
E (1), (2) \& (3)
