In the voting method, each member casts its vote on a draft resolution and the decision is deemed to be taken if the affirmative votes exceed a certain number or ratio. In simple majority, the affirmative vote requirement is more than half of all votes cast. In qualified majority, affirmative votes should be more than half of the votes cast. Finally unanimity, contrary to the general understanding, does not require affirmative votes of all members but simply seeks that no single negative vote is cast. So absences or abstentions are ignored which in turn means that members that do not effectively want to block (“veto”) a resolution may well prefer either not participating the voting or being present but casting a blank vote. As can be understood from the information given, the correct answer is C. Consensus is a model where decisions are taken without voting. Each and every member holds the right to express its opinion on a draft resolution. Objections, suggestions, proposals and amendment requests are voiced until a compromise and consent is reached at. At a point where no party raises further issues, the resolution is assumed to be assented. In cases where the matter in question directly relates a member State, the organizations may prefer consensus minus one procedure according to which that State is denied to have its say due to the principle nemo judex in sua causa (no-one should be a judge in his own cause).
