A capacitor of capacity \( \mathrm{C} \) is charged to a steady potential difference \( \mathrm{V} \) and connected in series with an open key and a pure resistor \( R \) . At time \( t=0 \), the key is closed. If \( \mathrm{I}= \) current at time \( t \), a plot of log I against \( t \) is as shown in (1) in the graph. Later one of the parameters i.e. V, \( \mathrm{R} \) or \( \mathrm{C} \) is changed keeping the other two constant, and the graph \( (2) \) is recorded. Then
(A) \( \mathrm{C} \) is reduced
(B) \( \mathrm{C} \) is increased
\( P \)
(C) \( R \) is reduced
(D) \( \mathrm{R} \) is increased
