The correct option is C big baggy yellow polo
When more than one adjective modifies a noun, then the adjectives are in the order: opinion, size, shape, condition, age, colour, pattern, origin, material, purpose.
Option A: 'Big' is the size, 'baggy' is the shape (or rather, out of shape), 'yellow' is the colour and 'polo' is the noun that is modified.
These words are in the order explained above: size, shape, colour.
Hence A is correct.
The rest of the options do not contain the required order of adjectives. Hence options B, C and D are incorrect.
