(D) Looking at the circuit diagram,let the nodes be $L, M, N, Z$. $1$. The first resistor $R$ is connected between $L$ and $M$. $2$. The second resistor $R$ is connected between $M$ and $N$. $3$. The third resistor $R$ is connected between $N$ and $Z$. $4$. There is a wire connecting $L$ to $N$,which means nodes $L$ and $N$ are at the same potential. $5$. There is a wire connecting $M$ to $Z$,which means nodes $M$ and $Z$ are at the same potential. Effectively,all three resistors are connected in parallel between the points $M$ and $N$. Therefore,the equivalent resistance $R_{eq}$ between $M$ and $N$ is given by: $\frac{1}{R_{eq}} = \frac{1}{R} + \frac{1}{R} + \frac{1}{R} = \frac{3}{R}$ $R_{eq} = \frac{R}{3}$

Three equal resistances each of value $R$ are joined as shown in the figure. The equivalent resistance between $M$ and $N$ is
