What does it mean to 'mock' someone?

To 'mock' someone means to deride or make fun of them, often in a way that is intended to belittle or insult. When you mock someone, you may imitate their actions or voice in a sarcastic manner or ridicule their opinions or characteristics, which can be hurtful. This term is commonly understood in both everyday conversation and formal contexts, including literature or discussions about social behavior.

The other options do not reflect this meaning. Admiring someone implies a sense of respect or approval, assisting someone means offering help, and comforting someone involves providing solace or support. Therefore, only deriding captures the essence of mocking accurately.
