The correct option is D excessive
The term "rampant" means especially of something unwelcome) flourishing or spreading unchecked, that is, excessively spreading. Hence, Option D is correct. Among the rest of the options, fashionable means characteristic of, influenced by, or representing a current popular style, chronic means persisting for a long time or constantly recurring, deep-rooted means firmly embedded in thought, behaviour, or culture, and so having a persistent influence. These do not express this meaning, hence incorrect.
