Detailed Solution:
The correct answer is “Salary and allowances of the Speaker of the Lok Sabha”.
The salaries and allowances of the President, the Vice President, and the Justices of the Supreme Court of India are charged on the Consolidated Fund of India, meaning they are not subject to the vote of Parliament.
However, the salary and allowances of the Speaker of the Lok Sabha are not charged on the Consolidated Fund and require the approval of Parliament.
