Explanation: Recognition of National and State Parties:

• The Election Commission registers political parties for the purpose of elections and grants them recognition as national or state parties on the basis of their poll performance.
• The other parties are simply declared as registered-unrecognised parties.
• The recognition granted by the Commission to the parties determines their right to certain privileges like allocation of the party symbols, provision of time for political broadcasts on the state-owned television and radio stations and access to electoral rolls.
