Concept:The phrase uses color and temperature imagery to suggest jealousy and hostility.
Explanation:The poet says his friends noticed his daring act with "green and frosty eyes."
The color green is commonly linked with envy, while frosty suggests coldness or unfriendliness.
These words reveal that the friends did not approve of what he did.
Their gaze was jealous, distant, and unwelcoming.
No other option carries this combined meaning of envy and coldness.
Therefore, the expression that best shows the friends' attitude is "green and frosty eyes."
Answer:C. Green and Frosty eyes
