d. lens essay

The answer is "A. character analysis "

The analysis of a character is when notes are made that can identify the main idea that surrounds this character. This analysis is done by evaluating the motivations, attitudes of the character and how it influences their characteristics and personality. The analysis may be something about how the character embodies the challenges of a developing boy, or about the good inherent in all human beings. Perhaps your character shows readers that even horrible people are able to redeem themselves and deserve forgiveness.

C. Soliloquy

Explanation:

A soliloquy is a device used in plays in which a character voices his thoughts to the audience, in this way, the audience has direct access to the reasons behind the actions of the character.This is how the audience comes to understand the behaviour of the character in question, his feelings and his state of mind. For example, in one of Macbeth's soliloquies he sees a dagger floating towards Duncan's room, this shows the audience that he is having hallucinations and he is not mentally well. The most important parts of the story are developed through soliloquies.
