Introduction:
In the context of governance and the functioning of a state, there are different bodies that play distinct roles. One of these bodies is the legislature, which is primarily responsible for law-making. However, it is important to note that there are other bodies as well which are not merely law-making bodies. In this case, the correct answer is option 'C', the legislature.

Explanation:
1. Judiciary:
The judiciary is one such body that is not merely a law-making body. While the judiciary does interpret and apply the law, it is not directly involved in the legislative process of creating laws. The judiciary ensures that the laws created by the legislature are upheld and applied in a fair and just manner. It acts as a check and balance on the legislature and the executive branch of government.

2. Army:
The army is another body that is not merely a law-making body. Its primary role is to safeguard the security and sovereignty of a nation. While the army may be involved in enforcing the law in certain situations, such as during times of emergency or war, its main function is to defend the country against external threats. The army operates under a separate set of rules and regulations, distinct from the laws created by the legislature.

3. Legislature:
On the other hand, the legislature is primarily responsible for law-making. It is the body that proposes, debates, and passes laws that govern society. The legislature represents the will of the people and is accountable for creating laws that reflect the needs and aspirations of the population. It plays a crucial role in the democratic process and ensures that the government operates within the framework of the law.

Conclusion:
While the judiciary and the army are important components of the governance structure, they are not primarily focused on law-making. The judiciary interprets and applies the law, while the army ensures national security. On the other hand, the legislature is the body that is directly involved in the process of creating laws. Therefore, the correct answer to the question is option 'C', the legislature.
