The question asks us to identify which of the rights mentioned are considered Fundamental Rights under the Constitution of India. Let's analyze each option:

1. Right to Work: This is not a Fundamental Right under the Indian Constitution. It is a Directive Principle of State Policy (DPSP) under Article 41. While the DPSPs aim to guide the state in policy-making for the welfare of the people, they are not justiciable in courts.
2. Right to Privacy: This is a Fundamental Right. Following the landmark Supreme Court verdict in the case of Justice K.S. Puttaswamy (Retd.) vs. Union of India, 2017, the Right to Privacy was declared a Fundamental Right under Article 21 of the Constitution, which protects life and personal liberty.
3. Right to Free and Compulsory Education in the Age Bracket of Six to Eighteen Years: This is inaccurate. The correct age bracket stipulated by the Constitution for free and compulsory education is six to fourteen years under Article 21A, making it a Fundamental Right. The age bracket provided in the question (six to eighteen years) is incorrect.

Considering the options, we find:

• 1 and 2: As evaluated, only the Right to Privacy (option 2) is a Fundamental Right. Right to Work is not.
• 2 only: This correctly identifies the only option that is a Fundamental Right.
• 2 and 3: While Right to Privacy is correct, the age bracket for education is incorrect as per the Constitution.
• 3 only: This option is incorrect due to the inaccurate age bracket.

Thus, the correct answer is 2 only, signifying the Right to Privacy as a Fundamental Right.
