In which of the following scenarios can a joint sitting of both Houses of Parliament be convened to resolve a deadlock?

Explanation

Under Article 108 of the Indian Constitution, a joint sitting of both houses can be convened by the President only in the case of a deadlock over an ordinary bill. There is no provision for a joint sitting for a Money Bill (as the Lok Sabha has overriding powers and Rajya Sabha must return it within 14 days) or a Constitutional Amendment Bill (which must be passed by each House separately with a special majority).
