And indeed there will be timeTo 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 dareDisturb the universe?In a minute there is timeFor decisions and revisions which a minute will reverse.
Which words best indicate that Prufrock feels uncertain?

The words "Do I dare?" best indicate that Prufrock feels uncertain.

Explanation:

In the poem “The Love Song of J. Alfred Prufrock”, author T. S. Elliot creates a speaker who is unfit to be a hero of romantic, traditional times. Prufrock has never fulfilled his desires. He is a lonely man who lives through others, who is insecure of his own appearance and ability to talk to women. His indecisiveness, his uncertainty, is expressed in the excerpt through the repetition of the words "Do I dare?" Prufrock cannot make up his mind. Should he try? Should he go and talk to people? Or will they be cruel, judgmental of him? His insecurity keeps him from daring to live.
