In K. S. Puttaswamy Case (2017), Supreme Court of India has held that right to privacy is a Fundamental Right and it is protected under Article 21 of the Constitution of India. Hence option (c) is the correct answer. The Court reasoned that privacy is an incident of fundamental freedom or liberty guaranteed under Article 21. The Court overruled M.P. Sharma, and Kharak Singh judgements, in so far as the latter did not expressly recognize the right to privacy.
