The energy of a system is given as $E(t) = \alpha^3 e^{-\beta t}$ , where $t$ is the time and $\beta = 0.3 \, \text{s}^{-1}$ . The errors in the measurement of $\alpha$ and $t$ are $1.2\%$ and $1.6\%$ , respectively. At $t = 5 \, \text{s}$ , the maximum percentage error in the energy is:

A
$4\%$
B
$11.6\%$
C
$6\%$
D
$8.4\%$
