The correct option is
C T-shirt: Blue; Jacket: Yellow; Dress: Green; Pants: Red
Based on the given image, the T-shirt is the shortest, and the pants are the longest item among the given set.
The jacket is longer than the T-shirt but shorter than the pants and the dress.
The dress is longer than the T-shirt and the jacket but shorter than the pants.
So, based on the image, we can arrange them from shortest to longest as—T-shirt, jacket, dress, and pants.
Based on the given clue, the red item is the longest and the blue item is the shortest of all the items.
The yellow item is longer than the blue item but shorter than both the green and the red items.
The green item is longer than both the blue and the yellow item but shorter than the red item.
So, based on the colors, we can arrange them from shortest to longest as—blue, yellow, green, and red.
Therefore, the correct colors of the clothing items will be T-shirt: Blue; Jacket: Yellow; Dress: Green; Pant: Red.
Hence, Option D is correct.
