An $\text{AC}$ source of $\text{RMS}$ voltage $20 \mathrm{~V}$ with internal impedance $Z_{s}=(1+2 j) \Omega$ feeds a load of impedance $Z_{L}=(7+4 j) \Omega$ in the figure below. The reactive power consumed by the load is
- $8 \; \mathrm{VAR}$
- $16 \; \mathrm{VAR}$
- $28 \; \mathrm{VAR}$
- $32 \; \mathrm{VAR}$
