Quizplus · Accepted Answer

Retinol activity equivalents (RAE) are a measure of vitamin A activity that takes into account the fact that different forms of vitamin A have different potencies. Preformed vitamin A (retinol) is the most potent form of vitamin A, while provitamin A carotenoids (such as beta-carotene) have to be converted by the body into retinol to have vitamin A activity. Therefore, A is the correct answer as it refers to the preformed vitamin A.
