Question

adding the suffix -tion to the word pollute makes a new word that means
\full of pollutants.\
\able to be polluted.\
\the action of polluting.\
\one who pollutes.\

Explanation:

Suffixes change a word's meaning. The suffix -tion usually forms nouns indicating an action. When -tion is added to "pollute" (a verb meaning to make something dirty or harmful), it forms "pollution", which is the action of polluting.

• "Full of pollutants" would be more related to a suffix like -ful (e.g., pollutant - ful is not a correct form here).
• "Able to be polluted" would be related to a suffix like -able (e.g., pollutable).
• "One who pollutes" would be related to a suffix like -er (e.g., polluter).

Answer:

"the action of polluting."
