Correct answer: A. Equal value of vote
Explanation: The principle “one person, one vote, one value” expresses political equality. It means that each eligible citizen gets one vote and that every vote has the same importance in deciding the result. A person’s wealth, education, job, caste, gender, or social position should not give the vote extra weight. Therefore, the equality most important at the time of voting is equal value of the vote, option A.
The other choices concern clothing, income, or housing, which are not the basic rule for counting votes. Citizens may differ greatly in these matters, but those differences must not become differences in political power. If one person’s vote counted more than another’s, some citizens would have greater influence over government. Equal voting value prevents that discrimination and connects democratic elections with equal citizenship.
