Read the sentence.
Sunny_sXe [5.5K]

Answer: D

Explanation: "less" almost always qualifies as an adjective, because it's describing a noun, that being support, which is a thing/idea.

You would use it as an adverb if you were using it to describe or add more information to a verb. Ex. "I've been trying to work <em>less</em> on the weekends." Work is a verb, so less would qualify as an adverb here.
