A deadlock between the Lok Sabha and the Rajya Sabha calls for a joint sitting of the Parliament during the passage of<br/>1. Ordinary Legislation<br/>2. Money Bill<br/>3. Constitution Amendment Bill<br/><br/>Select the correct answer using the codes given below:

1. Ordinary Legislation — Correct. Under Article 108, a deadlock between Lok Sabha and Rajya Sabha on an ordinary bill can be resolved by a joint sitting of Parliament.

2. Money Bill — Incorrect. A Money Bill can be introduced only in the Lok Sabha, and the Rajya Sabha has only recommendatory powers; hence no deadlock provision and no joint sitting.

3. Constitution Amendment Bill — Incorrect. Constitutional amendment bills under Article 368 must be passed separately by each House with the required special majority; joint sitting is not permitted.

Therefore, only 1 is correct.
