For the purpose of Lok sabha elections, our country is divided into ______
(A) 250 constituencies
(B) 543 constituencies
(C) 545 constituencies
(D) 500 constituencies

Hint:
The Indian parliament includes the President and the two Houses: The Rajya Sabha (Council of States) and the Lok Sabha ( House of the People). The President of India has the power to summon either the House of Parliament or to dissolve the Lok Sabha.

Complete solution:
As India has a vast diversity of caste, religion, state, language and culture, there can't be one person who can handle everything. He needs a person at a lower level so that those people can interact with citizens of India. So these constituencies are created to select members of parliament from each region so that those people can manage.
First Lok Sabha election was held in 1951. At that time there were 489 constituencies. So after that as no. If states increased, no. Of constituencies increased. By this point of view, option A is not appropriate.
Lok Sabha elections are held every 5 years. In 2014 there were 545 constituencies. So according to that option (D) is not appropriate.
But in 2018 there were only 543 constituencies voted as 1 in Meghalaya and 1 in Assam were removed. So after 2018, there are only 543 constituencies in Lok Sabha elections.


Hence, the correct answer is option B.

Note:
 India is a country which is divided into different states and constituencies. All these constituencies are run by one parliamentary system run under the constitution of India. The main leader of our country is the president who takes all the decisions of our country by keeping the well being of every Indian. Lok Sabha elections happen to choose members of parliament, and these MPs choose the president of India.
