Solution
The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion Coupling of PhN+H2 is an electrophilic aromatic substitution reaction, the cation is the electrophile and the activated arene is a nucleophile. Aniline is more electron-donating than phenol becasuse O is more electronegative than N, making it less basic (basic = ability to donate electrons).
Therefore, both assertion and reason are correct and reason is the correct explanation for assertion.
