Solution

The correct option is B $\frac{m_{3} F}{m_{1} + m_{2} + m_{3}}$
Acceleration, $a = \frac{F}{m_{1} + m_{2} + m_{3}}$
Forces acting on the combination of $m_{1}$ and $m_{2}$
$F - T = (m_{1} + m_{2}) a$
$T = F - (m_{1} + m_{2}) a$
$T = F - (m_{1} + m_{2}) (\frac{F}{m_{1} + m_{2} + m_{3}})$
$T = F (\frac{m_{1} + m_{2} + m_{3} - m_{1} - m_{2}}{m_{1} + m_{2} + m_{3}})$
$T = \frac{m_{3} F}{m_{1} + m_{2} + m_{3}}$
