A 1m long wire having tension of 100 N and of linear mass density 0.01 kg/m is fixed at end A and free at end B. The point C which is 20 cm from end B is constrained to be stationary. To create resonance in this wire, the minimum frequency of the tuning fork will be :
(A) 125 Hz
(B) 150 Hz
(C) 300 Hz
(D) 275 Hz
