The Right to Equality in the Indian Constitution is granted by five articles, from 14 to 18. Let`s break down each option and see why option 3 is the correct one:

Option 1: Article 16 to Article 20. This isn`t correct as Article 20 deals with protection in respect of conviction for offences, not equality.

Option 2: Article 15 to Article 19. This isn`t correct because Article 15 begins the right to equality but it doesn`t include Article 14 which is also a part of Right to Equality and Article 19 deals with freedom of speech, peaceful assembly etc., not directly connected to rights of equality.

Option 3: Article 14 to Article 18. This is the correct answer. Articles 14-18 deal directly with the Right to Equality, including equality before law, prohibition of discrimination, and abolition of untouchability and titles.

Option 4: Article 13 to Article 17. This is not correct because although Article 17 is about abolition of untouchability it does not include Article 18 which is also a component of Right to Equality. Also, Article 13 talks about laws inconsistent with or in derogation of the fundamental rights, which is not directly concerned with equality.
