All parties getting a chance to campaign is related to what?

Correct answer: Equal opportunity

Direct answer: A is correct. Democratic electoral competition is fair only when parties and candidates have a reasonable and lawful opportunity to present their ideas, programmes, and candidates to voters. Equal opportunity does not mean that every party will receive exactly identical attention or obtain the same number of votes. It means that the basic rules should not unfairly favour one party or prevent others from communicating with voters. B is wrong because taxation is not the principle described here. C is wrong because hereditary politics means leadership passed through family lines, not equal campaign access. D is wrong because providing campaign opportunities supports voter choice and does not stop voting. Campaign rules may still place lawful limits on time, spending, speech, or public order so that competition remains fair. Memory cue: equal chance to speak helps voters compare before they choose.
