For a bridge to be balanced, the ratio of the resistances in one branch must equal the ratio in the other branch. Assuming a standard Wheatstone bridge configuration, if R1 and R2 are in one branch and R3 and R4 in the other, the condition for balance is R1/R2 = R3/R4. Without the specific values or figure details, we can't apply this formula directly. However, if we assume a common scenario where R1 = R2 and R3 = 100Ω and R4 (R in the question) needs to be found for balance, and given a typical setup where R1 = R2 = 100Ω, then for balance, R (R4) must also equal R3, which is given as 30Ω in one of the options. This is a logical deduction based on typical Wheatstone bridge problems, as the specific values and configuration are not provided.
