The correct response is:
by emphasizing the growing unease among the congregation at Mr. Hooper's appearance and the message of his sermon.
In the passage, the congregation's reaction to Mr. Hooper's black veil illustrates their discomfort and the underlying theme of hidden sin and guilt. The veil serves as a powerful symbol that evokes fear and curiosity, indicating that Mr. Hooper himself may be concealing something significant. As the parishioners observe him, their wonder and amazement reflect their own potential guilt and the hidden sins within their lives. Mr. Hooper's steadfastness in wearing the veil during his sermon suggests an exploration of the idea that all individuals bear their own burdens of sin, which deepens the theme of underlying guilt among his listeners. The congregation's growing unease suggests that they are confronting their own hidden transgressions as they witness Mr. Hooper's unwillingness to reveal the face behind the veil.
