Answer

Brief Explanations:

A step - up transformer increases voltage. The relationship between voltages and number of turns in primary ($V_p$,$N_p$) and secondary ($V_s$,$N_s$) coils is $\frac{V_s}{V_p}=\frac{N_s}{N_p}$. In a step - up transformer, $N_s > N_p$, so $V_s>V_p$. It works with alternating current and doesn't convert DC to AC.

Answer:

C. The voltage of the secondary coil is greater than that of the primary coil.
