Detailed Explanation:

Fundamental Rights in India are divided into two categories: those available to all persons (citizens and non-citizens) and those available only to citizens.

Article 14 (Equality before law), Article 21 (Protection of life and personal liberty), and Article 25 (Freedom of religion) apply to all persons in India, including a British citizen.

Article 19(1)(g) (Freedom of trade, profession, and business) is available only to Indian citizens. Therefore, a British citizen staying in India cannot claim this right.
