The correct option is D: La primavera, el verano, el otoño, el invierno. This means in English: springtime, summer, autumn, winter. Option a) and b) are incorrect because "inverano" and "vierno" aren't real words. They don't exist in Spanish. Option c) is incorrect because the order of the seasons isn't right. Winter doesn't come after spring and summer doesn't come after autumn.
