It seems to me that you're just on another trip. I keep expecting you. Willy, dear, I can't  cry. Why did you do it? I search and search and I search, and I can't understand it, Willy.

Linda's closing remarks incorporate:

A. soliloquy.

Explanation:

A soliloquy is a device commonly used in plays. Its purpose is to have characters make their thoughts known to the audience by speaking out loud when they are alone or regardless of any hearers. Therefore, a soliloquy usually consists of a series of ideas, questions, or remarks, often connected in a way that mimics our thoughts. That is what we have in Linda's remarks. She is speaking regardless of whoever is hearing. In this case, she does have an audience - her dead husband. In a way, she is talking to him but, since he cannot hear her, she ends up talking to herself. Her questions will go unanswered.
