The President can dismiss a Cabinet Minister, who is also an MP, with the recommendation of the Prime Minister.

This power of dismissal of a Cabinet Minister is derived from the principle of collective responsibility. The Cabinet, including the Prime Minister and other Ministers, collectively holds the responsibility for the decisions taken by the government. If a Cabinet Minister fails to perform their duties or acts against the interests of the government, the Prime Minister can recommend their dismissal to the President.

Explanation:

1. Collective Responsibility:
- Collective responsibility refers to the concept that the Cabinet, including the Prime Minister and other Ministers, is collectively responsible for the decisions and actions of the government.
- This principle ensures that the government functions as a cohesive unit and maintains a unified stance on policies and decisions.
- It also ensures accountability, as Ministers are collectively responsible for the implementation of government policies.

2. Role of the Prime Minister:
- The Prime Minister is the head of the government and is responsible for the functioning of the Cabinet and its Ministers.
- The Prime Minister has the authority to recommend the dismissal of a Cabinet Minister to the President.
- This recommendation is usually made when a Minister fails to perform their duties, engages in misconduct, or acts against the interests of the government.

3. President's Role:
- The President, as the head of state, acts on the recommendations made by the Prime Minister.
- In the case of dismissing a Cabinet Minister, the President exercises the power of dismissal based on the recommendation received.
- The President's role is largely ceremonial, and they act on the advice of the Council of Ministers headed by the Prime Minister.

4. Judicial Review:
- The show cause notice issued to the Judiciary mentioned in option (c) is not applicable in this context.
- The dismissal of a Cabinet Minister is a political decision and falls within the domain of executive discretion.
- Judicial review is generally not applicable to political decisions made by the executive branch of the government.

Therefore, the correct answer is option 'B' - The President can dismiss a Cabinet Minister, who is also an MP, with the recommendation of the Prime Minister. This power is derived from the principle of collective responsibility and ensures the accountability and smooth functioning of the government.
