Final answer:
The constitutional crisis in the 1950s in India does not correspond to the laws mentioned. The correct law directly addressing political stability through legislative party membership is the Anti-Defection Law, enacted as the Tenth Schedule of the Indian Constitution in 1985.
Step-by-step explanation:
The constitutional crisis mentioned in the question, which took place in the 1950s in India, does not directly relate to any of the laws listed in the options provided. The first president of India, Rajendra Prasad, was involved in a situation concerning the Hindu Code Bill, but the crisis in question was not resolved by a specific law that clarified the conventions of cabinet government. However, the Anti-Defection Law mentioned as an option (d), was enacted much later in 1985 as the Tenth Schedule of the Indian Constitution. It was designed to address a different issue: the stability of governments by preventing political defections by party legislators.
The Anti-Defection Law, also known as the Tenth Schedule of the Constitution, was introduced in 1985. It aims to prevent political defections by legislators and provides for the disqualification of Members of Parliament or State Legislatures who defect from their political parties. This law helped establish stability and prevent political instability in India's government.
