If measured time period are \( T_{1}=8.01 \mathrm{~s} \) and \( T_{2}=8.41 \mathrm{~s} \) by a student who used stop watch having least count \( =0.01 \mathrm{sec} \), then find best reported time (in sec) is
(a) \( 8.2 \pm 0.2 \)
(b) \( 8.41 \pm 0.2 \)
(c) \( 8.21 \pm 0.01 \)
(d) \( 8.41 \pm 0.01 \)
