In a Wheatstone network, the resistances in cyclic order are P = 10 Ω, Q = 5 Ω, S = 4 Ω and R = 4 Ω. Then, for the bridge to balance,
A. 5 Ω should be connected in parallel to Q = 5 Ω
B. 10 Ω should be connected in series with Q = 5 Ω
C. 5 Ω should be connected in series with P = 10 Ω
D. 10 Ω should be connected in parallel to P = 10 Ω
