Find the synonym of the underline word.
The Arabic term from which the word ‘coffee’ derives is originally referred to the bitter quality of the beverage itself.

• Since a beverage is anything apart from water, so we are able to include coffee under beverages, so from the given options, we've got to seek out what coffee is. Since coffee may be a drink, the proper answer is option C, that is, drink.
• Option A is a plant. Though coffee comes from a plant, it doesn't mean that a beverage means plants. Therefore it's not the proper answer.
• Option B is substance. A substance refers to a thing. The substance also means material. However, it's not a synonym for a beverage.
• Option D is an infusion. An infusion could be a drink that's made by soaking leaves in water. An example of infusion is tea. Coffee is created from seeds and not leaves. Therefore, the proper synonym is not option D.

Hence, option C is the correct answer.
