In the signal flow graph of a closed loop system shown below, \(T_{D}\) represents the disturbance in the forward path.

The effect of the disturbance can be reduced by
(a) increasing \(\mathrm{G}_{2}(\mathrm{~s})\)
(b) decreasing \(\mathrm{G}_{2}(s)\)
(c) increasing \(\mathrm{G}_{1}(\mathrm{~s})\)
(d) decreasing \(\mathrm{G}_{1}(s)\)
