Final answer:
The suffix -tion transforms verbs into nouns, indicating the state or action related to the verb. Option number a is correct.
Step-by-step explanation:
The suffix -tion is used in English to transform verbs into nouns, and its meaning is generally related to the idea of 'state' or 'action'. When added to a verb, it turns the word into a noun that expresses the result or outcome of that verb.
For example, the verb 'inform' becomes 'information', meaning the state of being informed. Another example is ‘celebrate’ becoming ‘celebration’, referring to the action of celebrating or the state in which a celebration is occurring.
