Final answer:
The best example of figurative language in the given options is "He knew how to slither under her smoothly, like silk," which is a simile comparing Ted's interactions to the smoothness of silk.
Step-by-step explanation:
The best example of figurative language regarding Ted's interaction with his mother is: "He knew how to slither under her smoothly, like silk." This is an example of a simile, which compares two different things using 'like' or 'as'. In this case, Ted's actions or behaviour is being compared to silk, implying a smooth, perhaps even sneaky, manner of interacting without directly causing confrontation or disruption.
Similes often help readers visualize what is happening in the narrative and give deeper insights into characters and their relationships. Other forms of figurative language include metaphors, which make direct comparisons by stating something is something else, personification, which gives human characteristics to non-human objects, and hyperbole, which uses exaggeration for emphasis or effect.
It's important to distinguish between literal and figurative language. Literal language involves statements that mean exactly what they say, while figurative language requires interpretation beyond the words themselves to understand the meaning.
