The correct answer is option 4, which states that all of the sessions mentioned are part of our Parliament.

Option 1, the Monsoon Session, refers to the session that is held during the Monsoon season, typically from July to August. It is a crucial session where various bills and discussions take place.

Option 2, the Winter Session, is held during the winter season, usually from November to December. It is another important session where the Parliament discusses and debates on a wide range of issues.

Option 3, the Budget Session, is a session that is primarily focused on the Union Budget. It is held from February to May and includes the presentation and discussion of the budget.

Therefore, all of these sessions, the Monsoon Session, Winter Session, and Budget Session, are part of our Parliament`s functioning and play a significant role in the legislative process.
