An AC source of 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

1. $8 \; \mathrm{VAR}$
2. $16 \; \mathrm{VAR}$
3. $28 \; \mathrm{VAR}$
4. $32 \; \mathrm{VAR}$
