Answer:
D. -ion
Step-by-step explanation:
Affixes are morphemes we add to the word stem to create new word forms or new words. Suffixes are affixes that come after the word stem.
We can solve this question by eliminating the incorrect options. We need to find the suffix used to create nouns. Suffixes -ic and -ible are used to create adjectives (e.g. chaotic, edible). Suffix -ly is used to create adverbs and adjectives (e.g. loudly, lovely). That leaves us with option D as the only correct one. We can prove this by creating some nouns with it, for example: adoration, creation, extinction, etc.
