Which Article of the Constitution of India safeguards one's right to marry the person of one's choice?

Article 21 is the correct answer because the Supreme Court, in the *Shafin Jahan v. Asokan K.M. (2018)* case, ruled that the right to marry a person of one's choice is an integral part of the "Right to Life and Personal Liberty." While Article 19 is a tempting choice as it protects various individual freedoms, it does not specifically encompass the personal autonomy and dignity inherent in choosing a spouse, which falls under the judicially expanded scope of Article 21. This question tests the core concept of how the judiciary interprets Fundamental Rights to include unenumerated rights essential for human dignity.
