Final answer:
The Right to Life and Personal Liberty cannot be restricted only on the grounds of reasonable restriction in the interest of the sovereignty and integrity of India. Other rights, like the Right to Freedom of Speech and Expression and the Right to Freedom of Religion, are subject to reasonable restrictions. The Right to Equality can also face restrictions for affirmative action so the correct answer is option (d).
Step-by-step explanation:
The fundamental right that cannot be restricted solely on the grounds of reasonable restriction in the interest of the sovereignty and integrity of India is d) Right to Life and Personal Liberty. The Right to Life and Personal Liberty is a core human right that is granted to every individual and is considered inviolable by the Constitution. This right cannot be restricted except through the procedure established by law, and even then, the restriction has to pass the test of legality, need, and proportionality under the Indian Constitution.
However, reasonable restrictions can be imposed on other rights, such as Right to Freedom of Speech and Expression and Right to Freedom of Religion under certain conditions laid down in the Constitution to maintain public order, morality and the sovereignty and integrity of India. The Right to Equality could also face restrictions in exceptional circumstances, such as affirmative action for the protection of marginalized groups.
