Explanation: This question involves a mix of historical facts and legal provisions related to life insurance in India. Let's break down each statement to understand the context and verify their accuracy.
1. **Muhammad Ghori had sons**: This statement is false. Muhammad Ghori, also known as Muhammad of Ghor, was a ruler of the Ghurid Empire in the 12th century. He did not have any sons. His empire was eventually taken over by his slave, Qutb-ud-din Aibak, who founded the Delhi Sultanate.
2. **The tomb of Ghiyas-ud-din Tughlaq was built by the Tughlaq Dynasty**: This statement is true. Ghiyas-ud-din Tughlaq was the founder of the Tughlaq Dynasty, which ruled parts of India in the 14th century. His tomb, known as the Tughlaqabad Fort, was indeed built by the Tughlaq Dynasty. The fort and tomb complex are located in Delhi and are significant historical monuments.
3. **Section 6 of the MWP Act covers life insurance plans**: This statement is true. The MWP Act, or the Maternity Benefit (Amendment) Act, 2017, includes provisions related to life insurance for married women. Section 6 of the Act ensures that any married woman, including divorced persons and widowers, can take a life insurance policy under the Act. This provision aims to provide financial security and support to women in various marital statuses.
The correct answer is (D) Only 2, 3, as these statements are true based on historical and legal facts. The first statement is false, and therefore, any option that includes it is incorrect.
Understanding these statements requires knowledge of medieval Indian history and the legal framework governing life insurance in India. The Tughlaq Dynasty's contributions to architecture and the provisions of the MWP Act are important aspects of Indian general knowledge and are often tested in competitive examinations.
