Solution

The correct option is A $300 cos (15 t + \frac{4 π}{3})$
$V_{i} = 2 cos (15 t + \frac{π}{3})$
Voltage gain: $A_{v} = \frac{V_{o}}{V_{i}}$ where $V_{o}$ is the output voltage
$∴ V_{o} = A_{v} \times V_{i} = 150 \times 2 cos (15 t + \frac{π}{3})$
$= 300 cos (15 t + \frac{π}{3})$
In CE amplifier, $V_{o}$ and $V_{i}$ have a phase difference of $π$ between them.
$∴ V_{o} = 300 c o s (15 t + \frac{π}{3} + π)$
$= 300 cos (15 t + \frac{4 π}{3})$
