Here's why each option is problematic:
* A) Recounting the plot of a Greek myth: While using myths can be a powerful rhetorical tool, it's unclear how directly it would connect to the idea of the British deceiving the speaker's countrymen. The connection needs to be made explicit.
* B) Making references to slavery: This is a strong and loaded topic. While it could potentially relate to deceit, it's unclear how it would be specifically applied to the British in the context of the speaker's argument. It's crucial to know what the speaker is arguing about to understand the relevance of this point.
* C) "p": This is incomplete and doesn't provide any context.
To help you answer the question, please provide the following:
* Who is the speaker? This will help determine their perspective and the audience they are addressing.
* What is the speaker's overall argument? This will provide the context for understanding how the techniques are used.
* What are the speaker's specific claims about the British deceiving their countrymen? This will clarify the idea being emphasized.
Once you provide this information, I can help you analyze how the speaker uses those techniques to emphasize their idea.
