The correct answer is option 'B': The recess of a House of the Parliament is defined as the period spanning between the prorogation of a House and its reassembly in a new session.

Explanation:
The recess of a House of Parliament refers to the period of time when the House is not in session. It is a temporary period of adjournment during which Members of Parliament are not required to attend the proceedings. The recess serves as a break in the parliamentary calendar and allows MPs to engage in other activities such as constituency work or personal commitments.

During the recess, the House is prorogued, which means that the current session is formally ended. Prorogation is the act of ending a session of Parliament by the monarch (or the Governor-General in some countries) on the advice of the Prime Minister or the Speaker of the House. It marks the conclusion of all business and debates in the current session.

Key points:
- The recess of a House of Parliament is the period between the prorogation of a House and its reassembly in a new session.
- Prorogation is the formal end of a session of Parliament.
- During the recess, MPs are not required to attend parliamentary proceedings.
- The recess allows MPs to engage in other activities such as constituency work or personal commitments.

Significance of the recess:
1. Legislative break: The recess provides a temporary break in the legislative activity of the House. It allows MPs to take a break from the demanding schedule of parliamentary sessions and engage in other important duties.
2. Constituency work: MPs can use the recess period to focus on their constituency work. They can visit their respective constituencies, interact with constituents, and address their concerns and issues.
3. Committee work: The recess also provides an opportunity for MPs to engage in committee work. Parliamentary committees play a crucial role in examining bills, conducting inquiries, and scrutinizing government activities. The recess allows committee members to dedicate more time to their committee responsibilities.
4. Policy research and development: MPs can utilize the recess period for policy research and development. They can study and analyze important issues, gather relevant information, and develop policy proposals for consideration in the next session.
5. Personal commitments: The recess allows MPs to spend time with their families, take vacations, or attend to personal commitments that may be difficult to manage during the regular session.

In conclusion, the recess of a House of Parliament is the period between the prorogation of a House and its reassembly in a new session. It serves as a temporary break in the parliamentary calendar and provides MPs with an opportunity to engage in constituency work, committee activities, policy research, and personal commitments.
