Im not sure if its nouns...
I don't understand, what are the topic choices, are there any to begin with?
The answer is about overcooked meat so D. overcooked is the correct answer because overcooked was modifying the meat and accommodated was utilized as a verb not a verbal(participle)
I hope this greatly helps you! :)
C. Symbol
Subject is the focus of the literature/art, context is what it's about or the surrounding meaning, theme is the subject or topic of lit or a work of art (though it can also be a main idea).
Symbol is the most correct answer, because it is a <em>thing, </em>object or detail, that represents an idea, as said.
