Correct answer: D. Abolition of untouchability
Explanation: Direct answer: Option D is correct. The Right to Freedom includes important freedoms such as speech and expression, peaceful assembly, forming associations, movement, residence, and choosing a profession or occupation, along with protections of personal liberty. Abolition of untouchability belongs to the Right to Equality, especially the constitutional protection against untouchability, not to the list of freedoms. Follow the classification: speaking is expression; gathering without violence is peaceful assembly; selecting lawful work is freedom of profession; removing untouchability is equality before the law and equal social status. Option A is wrong because expression is a recognised freedom, subject to reasonable legal restrictions. Option B is wrong because peaceful assembly is included. Option C is wrong because choosing a profession is included, although lawful regulation may apply. Option D is correct because it belongs to equality. Memory cue: keep the Fundamental Rights groups separate—untouchability points to Equality, while speech, assembly and profession point to Freedom.
