Answer
A is false but R is true.
Explanation — Electrolytes which allow small amounts of electricity to flow through them are called weak electrolytes. These are poor conductors of electricity. Hence the assertion (A) is false.
Substances which are composed of only molecules are non electrolytes, they do not allow any current to flow through them. For example, Benzene, glucose.
Hence the reason (R) is true.
