Correct answer
CBoth A and R are true and R is the correct explanation of A

Step-by-step explanation

Iodide ion is a powerful nucleophile and hence reacts rapidly with RCl to form RI. Further because I− ion is a better leaving group than Cl− ion, therefore , RI is more rapidly hydrolysed than RCl to form ROH.
