What change occurs as a result of adding un- to fortunate in paragraph 4?

C). The word takes an opposite meaning.

Explanation:

A Prefix is defined as a morpheme that is added at the beginning of a root word to modify its meaning. The root fortunate gives the meaning 'auspicious, favored by fortune, or having by good luck' while the prefix 'un-' means 'not, negative, lacking, or absent.' Thus, the addition of the prefix 'un-' to the word 'fortunate' reverses its meaning in the paragraph and it conveys the opposite sense i.e. 'not favored by fortune or resulting in misfortune.' Therefore, option C is the correct answer.
