Final answer:
The correct answer is 'better' (option C).
Step-by-step explanation:
In this sentence, we are comparing two cakes, the carrot cake and the red velvet cake. To indicate that the carrot cake is superior to the red velvet cake, we use the comparative form of the adjective "good," which is "better." Option C correctly fills the blank in the sentence.
Example: The carrot cake is better than the red velvet cake because it has a rich and moist texture.
Adjectives with two syllables can form the comparative either by adding -er or by preceeding the adjective with more. These adjectives form the superlative either by adding -est or by preceeding the adjective with most. In many cases, both forms are used, although one usage will be more common than the other.
Irregular modifiers take the comparative form by becoming another word entirely. Good and well become better. Bad and badly become worse. Superlative modifiers are used to compare one thing to two or more things.
We use a comparative adjective to express how two people or things are different, and we use a superlative adjective to show how one person or thing is different to all the others of its kind. For example, Mick is taller than Jack. Mick is the tallest person in the family.
