$3-4.$ Consider this transient RLC circuit:

$3.-$If the switch closes at time $t=0,$ what is the form of the transient current $i_L(t)$ for $t0?$

A$.i_L(t)=e^{-4t}[D_{1}cos(3t)+D_{2}sin(3t)],A$

B$.i_L(t)=2\mathrm{.}5+e^{-4t}[D_{1}cos(3t)+D_{2}sin(3t)]A$

C$.i_L(t)=B_1{e}^{-5t}+B_{2}t{e}^{-5t}A$

D$.i_L(t)=2\mathrm{.}5+B_1{e}^{-5t}+B_{2}t{e}^{-5t}A$

E$.i_L(t)=A_1{e}^{-7t}+A_2{e}^{-t}A$
