Charge in $2 \mu F$ Capacitor $=300 \mu C$
Charge in $3 \mu F$ Capacitor $=360 \mu C$
when $1.5 \mu F$ falls on the circuit ends, $Re-distribution$ of charge now will be$:$
Charge in $2 \mu F$ Capacitor $=300-x \mu C$ Charge in $3 \mu F$
Capacitor $=360-x \mu C$ Charge in $1.5 \mu F$ Capacitor $=x \mu C$
By Kirchoff Voltage Law$:$
$\frac{x}{1.5}=\frac{300-x}{2}+\frac{360-x}{3}$
which gives $x=180 \mu C$
Therefore Answers are $A, B \& C$
