A mass m is suspended separately by two different springs of spring constant K1 and K2 gives the time-period \[{{t}_{1}}\] and \[{{t}_{2}}\]respectively. If same mass m is connected by both springs as shown in figure then time-period t is given by the relation                    [CBSE PMT 2002]

A. \[t={{t}_{1}}+{{t}_{2}}\]
B. \[t=\frac{{{t}_{1}}.{{t}_{2}}}{{{t}_{1}}+{{t}_{2}}}\]
C. \[{{t}^{2}}={{t}_{1}}^{2}+{{t}_{2}}^{2}\]
D. \[{{t}^{-2}}={{t}_{1}}^{-2}+{{t}_{2}}^{-2}\]
