C Correct answer
Explanation

Tulip, daisy, and crocus are exclusively flowers. Iris is the outlier because it has dual meanings - it's both a flower and a part of the human eye (the colored part). This makes it different from the other three options which only have one meaning in common usage. The word association pattern is the key here.
