To "deprecate" someone or something means to:

To "deprecate" someone or something means to belittle or criticize. The term originates from the Latin "deprecatus," which means to pray against or to express disapproval. In contemporary usage, it conveys a sense of showing disapproval, minimizing the value or importance of a person, idea, or thing. For example, when someone deprecates a proposal, they are not merely expressing disagreement; they are actively diminishing its worth or validity, often implying that it should be ignored or scorned.

The other choices reflect positive or supportive attitudes, which contrasts sharply with the meaning of deprecate. Appreciating something highly, encouraging, or advocating strongly involves promoting or valuing it, rather than expressing disapproval or belittlement.
