What is the correct meaning of the state power to regulate economic or secular activities under Article 25?

Correct answer: The state can regulate non-religious administrative activities associated with religion by law

The direct answer is D: the State may regulate by law non-religious, secular administrative activities associated with religion. Article 25 protects freedom of conscience and the freedom to profess, practice, and propagate religion, but it is subject to constitutional limits. A useful distinction is between the religious act itself and connected secular matters such as management of property, financial administration, public access, or other non-religious arrangements. The State may regulate the secular part through law; this does not mean it can simply abolish every form of worship or take away conscience. Option D is correct because it states this limited regulatory power. Option A is too broad: the State cannot end every worship method merely because Article 25 exists. Option B is wrong because secular regulation does not allow the State to declare an official religion. Option C is wrong because Article 25 protects, rather than removes, freedom of conscience. The exam cue is worship versus management: religious freedom is protected, while associated secular administration may be regulated lawfully.
