The black and white cat climbed the fence.
C. Instance, because you are using a dash to separate the list from the rest of the sentence
The correct answer is the role of adjective. Both non-finite verbs can perform the role of adjective in a sentence. The following examples show this role:
Present participle as adjective, which can be recognized from its "-ing" ending:
Look at the <u>reading</u> boy.
Past participle as adjective, which are formed by adding "-ed" to the verb:
Look at the <u>washed</u> car.
