Q1. Choose the correct opening block for an examination-style notice issued by the Office of the Principal of a college to announce a change in library timings.
Explanation
A formal notice should begin with the issuing authority, the label NOTICE, a clear heading, and the date. The cue is an official college announcement about changed library timings. Option A alone gives a notice-style opening block; the other options use personal-letter, application, or formal-letter formats.
