The formula of the rate constant -

\mathrm{k=A e^{-E_{a} / R T}}
(Where A is called a pre-exponential factor)

\mathrm{if, k=A\ then\ \mathrm{e^{-E_{a} / R T }=1}}

\Rightarrow \mathrm{-E_{a} / R T =0}

\Rightarrow \mathrm{1 / 0 =T}

\Rightarrow \mathrm{T =\infty }


So, The absolute temperature is infinity.

Therefore, option(3) is correct
