The idea of ‘Zero Hour’ was introduced in parliamentary democracy by

Great Britain
India
United States of America
None of the above

The correct answer is (a).

Zero Hour is a period of time in the Indian Parliament when members can raise any issue of public importance. It is held at the beginning of each day’s session, immediately after the Question Hour. The idea of Zero Hour was introduced in the Indian Parliament in 1950.

The idea of Zero Hour was borrowed from the British Parliament, where it is known as “Urgent Questions”. Urgent Questions are questions that are asked on a matter of urgent public importance. They are usually asked at the beginning of the day’s session, and the government is required to give a reply within 24 hours.

The idea of Zero Hour was introduced in the Indian Parliament in order to give members an opportunity to raise important issues that could not be raised during the Question Hour. The Question Hour is a period of time when members can ask questions to the government. However, the Question Hour is limited to a certain number of questions, and it is not always possible for members to raise all of the issues that they want to raise.

Zero Hour has been used to raise a number of important issues, including corruption, inflation, and the state of the economy. It has also been used to raise issues that are of particular interest to a particular group of people, such as farmers, students, and workers.

Zero Hour has been criticized for being a time for members to make speeches that are not relevant to the issues at hand. It has also been criticized for being a time for members to score points against the government. However, Zero Hour remains an important part of the Indian Parliament, and it is a valuable tool for members to raise important issues.

The other options are incorrect because:

(b) India did not introduce the idea of Zero Hour. It was introduced in the British Parliament.

(c) The United States of America does not have a Zero Hour.

(d) None of the above is the correct answer.
