B)  0.05 $\mu \mathrm { F }$, 15 V 
C)  0.15 $\mu F$, 10 V
D)  0.15  $\mu \mathrm { F }$,  20 V

Quizplus · Accepted Answer

In parallel connection, the total capacitance is the sum of individual capacitances, so $0.05 \mu F + 0.1 \mu F = 0.15 \mu F$. Each capacitor in a parallel circuit drops the same voltage as the source, which is 20 V.
