A: Elena asks her boss for extra pay for the additional hours she worked
<span>The sentence that does not contain any errors is D. Whose muddy shoes are these on my clean kitchen floor? This is because the possessive pronoun whose is correctly used here. In A, it should be Greg's, and not Gregs'. In B, it should be actresses' families, and not actresses families'. In C, it should be it's, because that means it is, and not its, which is a possessive pronoun (the dog wagged its tail).</span>
I would say (b) because this answer is the most focused. It's also a topic which would easily fit in a five paragraph essay, while the others would most likely require extensive research and would only fit in an at least ten page paper.
