In autumn, the chlorophyll in leaves breaks down as the days get shorter and cooler. As a result, the green color fades, revealing the colors of other pigments such as carotenoids (yellow, orange and brown) and anthocyanins (reds and purples) that have been present in the leaves all along. So, option A is the correct answer.
