The Constitution of Bangladesh, adopted in 1972, embodies a number of fundamental principles that serve as the foundation for the state's governance and legal framework. Among these principles, four key state principles are outlined in Article 8 of the Constitution. These principles are nationalism, socialism, democracy, and secularism.

1. **Nationalism** emphasizes the importance of the Bangladeshi identity and the collective interests of its people, fostering a sense of unity and patriotism.

2. **Socialism** aims to promote social justice, equality, and the welfare of all citizens, ensuring that wealth and resources are distributed in a manner that benefits the disadvantaged and reduces inequality.

3. **Democracy** is central to the governance of the state, ensuring that the government is accountable to the people through free and fair elections, and protecting fundamental rights and freedoms.

4. **Secularism** guarantees freedom of religion and the separation of religion from the state, ensuring that the government remains neutral in religious matters and promotes tolerance among different faiths.

These four principles collectively reflect the aspirations of the Bangladeshi people post-independence and form the bedrock of the nation’s political and social ethos. Thus, the correct answer to the question regarding the number of state principles in the 1972 Constitution of Bangladesh is indeed Option C: 4.
