(B) The formula for the angular momentum $(L)$ of an electron in the $n^{th}$ orbit is given by Bohr's postulate:$L = mvr = \frac{nh}{2\pi}$Given that the orbit number $n = 5$,we substitute this value into the formula:$L = \frac{5h}{2\pi}$Calculating the value:$L = 2.5 \frac{h}{\pi}$Therefore,the correct option is $B$.
