Answer:
The correct answers are "-able" and "-ous"
Step-by-step explanation:
The root desire can have different suffixes that will determine the function of the word.
For example, with the suffix "-able", the noun desire is changed into the adjective "desirable". The meaning of the adjective is something that has pleasing characteristics or qualities.
Also, if we add the suffix "ous" to the word desire, we come up with another adjective, "desirous", that means that you want something very much. This adjective is used with the preposition "of": "desirous of something".
