What among the following is not a power or function of the Speaker of Lok Sabha?

The correct answer is Option C: The Speaker of the Lok Sabha must resign from the membership of his party after being elected as a Speaker

The Speaker of the Lok Sabha in India has several powers and functions, but it's important to note that they do not resign from their party after being elected as a Speaker. Here's an explanation of the other options:

- Option A: When there is a deadlock in a vote, the Speaker can cast his casting vote to break the deadlock. This is a legitimate power of the Speaker.

- Option B: The Speaker decides whether a bill is a money bill or not. This is also one of the powers and functions of the Speaker.

- Option D: The Speaker of the Lok Sabha holds a higher rank than all cabinet ministers except the Prime Minister and Deputy Prime Minister. This is another valid function of the Speaker.

However, Option C: stating that the Speaker must resign from the membership of his party after being elected as a Speaker is not accurate. The Speaker is expected to be impartial and is generally expected to sever their active ties with their political party while presiding over the proceedings in the Lok Sabha, but they do not formally resign from the party.

So, the correct answer is Option C: The Speaker of the Lok Sabha must resign from the membership of his party after being elected as a Speaker is not a power or function of the Speaker.
