A. dreams and ambition by using metaphors.

Explanation: a metaphor is a comparison between things that aren't obviously related with each other. In the given excerpt from Act II of "Hamlet" by William Shakespeare, we can see the use of metaphors to compare (and describe the nature of) dreams (by comparing them to ambition and shadow: "Which dreams, indeed, are ambition" and "A dream itself is but a shadow") and ambition (by comparing it to a shadow's shadow: "and I hold ambition of so airy and light a quality that it is but a shadow’s shadow").

a. Dreams and ambition by using metaphors.

Explanation:

A metaphor is a figure of speech that asserts that one element (a person, an animal, a thing, a quality, an event, etc.) is similar to another element that in reality, or literally speaking, are not related in any way or are very different. In the excerpt, the characters use metaphors when comparing dreams to ambition and to a shadow, and by the use of these metaphors, Hamlet and Guildenstern give the element "dream" a deeper meaning than the literary or scientific meaning.
