The term `Fraternity` in the Preamble of the Indian Constitution refers to the idea of `brotherhood`. It signifies a sense of unity, equality, and solidarity among all the citizens of India. It emphasizes the importance of treating each other with respect and compassion, irrespective of caste, religion, gender, or any other differentiating factor.

Option 1 - `Friendliness` is not an accurate interpretation of `Fraternity` as it does not fully capture the depth of the relationship and bond that fraternity signifies.

Option 2 - `Statehood` is unrelated to the concept of fraternity in the context of the Indian Constitution.

Option 3 - `Love and affection` may have elements of fraternity, but it does not capture the full essence of the term.

Overall, option 4 - `brotherhood` is the best description that aligns with the meaning of `Fraternity` in the Preamble of the Indian Constitution.
