Correct answer choice is:
C. Happiness.
Step-by-step explanation:
A suffix is a word or a combination of characters added to the end of a word to create a distinct word or to modify the morphological use (or part of speech) of the original speech. The suffix varies the definition of the word. For instance, the action word "read" is formed into the noun "reader" by affixing the suffix -er. Non all suffixes can be attached to all origins.
