The correct answer is b. It shows the reader how nervous and anguished the narrator is.
The use of personification in this excerpt, particularly in the expression of the narrator's senses desiring to "veil themselves," emphasizes the emotional turmoil and inner conflict the narrator is experiencing. The trembling of his hands and the repeated murmuring of "O love! O love!" further illustrate his anxiety and distress, conveying a deep sense of vulnerability and longing.
