The correct answer is: a) Greater autonomy within India.
The legacy of the freedom movement in Meghalaya influenced its later demand for greater autonomy within India. This is because the freedom movement in Meghalaya was largely based on the desire for greater self-determination for the Khasi people. The Khasi people were not satisfied with the level of autonomy that they had under British rule, and they wanted to have more control over their own affairs. After India gained independence, the Khasi people continued to demand greater autonomy, and this eventually led to the creation of the state of Meghalaya in 1972.
Option b) is incorrect because the Khasi people did not want to separate from India. They wanted to have greater autonomy within India, but they did not want to secede from the country.
Option c) is incorrect because the Khasi people did not want to merge with Bangladesh. They were not interested in joining Bangladesh, and they wanted to remain a part of India.
Option d) is incorrect because the Khasi people did not want to have religious reforms. They were satisfied with their traditional religion, and they did not want to change it.
