Solution

The correct option is B 57
Carbon has an atomic number of 6.
Isotopes of carbon are: $^{12} C,^{13} C,^{14} C$

$\begin{matrix} S y m b o l & N e u t r o n s & P r o t o n s & E l e c t r o n s^{12} C & 6 & 6 & 6^{13} C & 7 & 6 & 6^{14} C & 8 & 6 & 6 21 & 18 & 18 \end{matrix}$
$⟹ 21 + 18 + 18 = 57$
