Three arrangements are shown in figure.
(A) A spring of mass m and stiffness k
(B) A block of mass m attached to massless spring of stiffness k
(C) A block of mass m/2 attached to a spring of mass of mass m/2 and stiffness k
If T1, T2 and T3 represent the ** of oscillation in the three cases respectively. then identify the correct relation
(a) T1 < T2 < T3
(b) T1 < T3 < T2
(c) T1 > T3 > T2
(d) T3 < T1 < T2
