Carnation (\textit{Dianthus caryophyllus}) cut flowers are known to exhibit a physiological phenomenon called "sleeping disorder" or "sleepiness", where the flowers fail to open properly after harvest. This is a common post-harvest disorder and is typically caused due to ethylene sensitivity or improper storage and handling conditions.

Option (C) Chrysanthemum: Incorrect. Not commonly associated with sleeping disorder.
Option (D) Tulip: Incorrect. Tulips have different post-harvest concerns.
