The correct answer is (c) 27

For explanation: Capacitive reactance XC = 1/2πfC = 1/(6.28×50×100×10^-6)=31.83Ω. Capacitive susceptance BC = 1/XC = 1/31.83 = 0.031S. Conductance G=1/R = 1/50 = 0.02S. Total admittance Y=√(G^2+Bc^2)=√(0.02^2+0.031^2)=0.037S. Total impedance Z = 1/Y = 1/0.037 = 27.02Ω.
