Answer
A is true but R is false.
Explanation— The principle of fountain experiment is to show the great solubility of the HCl gas. Hence the assertion (A) is true.
The blue litmus solution turns red due to the acidic nature of hydrogen chloride gas in the Fountain experiment. Hence reason (R) is false.
