The correct answer is option 'D', which means that a recognised political party is one that is registered with the Election Commission of India, is given a unique Election symbol, and gets some other facilities recognised by the Election Commission. Let's explore each of these factors in detail:

1. Registered with the Election Commission of India:
To be a recognised political party in India, a party must be registered with the Election Commission of India. This registration process involves providing the necessary documents, such as the party's constitution, details of its office-bearers, and financial accounts. Once registered, the party is recognized as a legitimate political entity.

2. Given a unique Election symbol:
A recognised political party is also given a unique symbol by the Election Commission of India. This symbol serves as the party's identity on the ballot paper during elections. It helps voters easily identify and associate a party with its symbol.

3. Other facilities recognised by the Election Commission:
In addition to registration and symbol allocation, a recognised political party in India is entitled to various facilities provided by the Election Commission. These facilities include:

a) Allotment of free broadcast time on Doordarshan and AIR (All India Radio) during elections to convey their messages to the public.
b) Permission to set up election booths and polling agents at polling stations to ensure fair and transparent voting.
c) Access to the electoral rolls and other relevant information to assist in campaign planning and voter outreach.
d) Financial benefits, such as reimbursement of expenses incurred during elections, subject to certain conditions.

These facilities are granted to recognised political parties to ensure a level playing field and promote democratic participation in the electoral process.

In conclusion, a recognised political party in India is one that is registered with the Election Commission, is given a unique Election symbol, and receives various facilities recognized by the Election Commission. These factors establish the legitimacy and status of a political party in the Indian electoral system.
