The correct answer is option 1: Article 33. Under Article 33 of the Constitution of India, the fundamental rights of members of the Armed Forces can be specifically restricted. This means that the government has the power to impose certain limitations on the exercise of fundamental rights, such as freedom of speech, assembly, or movement, for members of the Armed Forces. This is done in the interest of discipline and good order within the Armed Forces.

Option 2: Article 19 is incorrect. Article 19 guarantees certain fundamental rights to all citizens, such as freedom of speech, assembly, and movement, but it does not specifically address the restriction of these rights for members of the Armed Forces.

Option 3: Article 21 is incorrect. Article 21 guarantees the right to life and personal liberty, but it does not specifically address the restriction of fundamental rights for members of the Armed Forces.

Option 4: Article 25 is incorrect. Article 25 guarantees freedom of religion, but it does not specifically address the restriction of fundamental rights for members of the Armed Forces.

Therefore, the correct answer is option 1: Article 33.
