$\begin {array} {1 1} (A)\;10\Omega & \quad (B)\;45\Omega \\ (C)\;61\Omega & \quad (D)\;100\Omega \end {array}$

The range of equivalent resistances possible to generate using these is

$ \large\frac{15}{3} $$ohms$ to $ 30 \times 3\: ohms.$ Since variable resistors have a continuous range,

equivalent resistors have a continuous range. Hence, one can obtain all values

between $5\: ohms\: to\: 90\: ohms.$
