The question asks which authority publishes education regulations (for pharmacy education and practice) in the official gazette. Instead of recalling the fact directly, let's work it out by first pinning down what "publishing in the official gazette" actually means legally, and then checking which body has that power.
Only the Central Government has the constitutional and statutory authority to notify regulations in the official gazette; every other option either administers policy, enforces rules, or merely recommends them.
Therefore, the correct answer is Central government.
