Correct : c

The sequence walk → jog → sprint shows an increasing level of intensity, where each action is stronger or faster than the previous one.
In the same way, we need to find a word that shows increasing emotional intensity in the sequence:
bothered → _______ → daunted

Here is what each word means:

• Bothered – slightly upset or disturbed.
• Fazed – noticeably disturbed, shaken, or upset; stronger than "bothered."
• Daunted – intimidated or overwhelmed; stronger than "fazed."

So the correct increasing order of emotional intensity is:
bothered → fazed → daunted
Therefore, the appropriate word to fill the blank is (c) fazed.
