Final answer:
The line from "Totally like whatever, you know?" that represents the proper use of syntax is "Even when those sentences aren't like questions? You know?"
A is correct
Step-by-step explanation:
The line from "Totally like whatever, you know?" that represents the poet's ability to apply proper use of syntax is option A: Even when those sentences aren't like questions? You know?
In this line, the poet uses correct sentence structure and word order to ask a question. The subject "those sentences" comes before the verb "aren't" and the question mark is placed at the end to indicate a question. This demonstrates the poet's understanding and application of syntax rules in writing poetry.
