Read the excerpt below and answer the question.

And indeed there will be time
To wonder, "Do I dare?" and, "Do I dare?"
Time to turn back and descend the stair,
With a bald spot in the middle of my hair—
[They will say: "How his hair is growing thin!"]
My morning coat, my collar mounting firmly to the chin,
My necktie rich and modest, but asserted by a simple pin—
[They will say: "But how his arms and legs are thin!"]
Do I dare
Disturb the universe?
In a minute there is time
For decisions and revisions which a minute will reverse.

What can you infer about Prufrock based on these lines?

He considers himself an important person.
He feels anxious about aging.
He enjoys drawing attention to himself.
He is unfamiliar with customs of polite society.

What appears to be causing the speaker in the excerpt to pay so much attention to his own appearance is public attention; he thinks about the criticism others might make by watching him from afar.

This criticism, at the same time, causes him to ponder about time and the effects it has on his image, which is evidenced with his comment about "a bold spot" in the middle of his hair and his "thin arms and legs".
