I would say the correct answer is C. She filled her living room with dozens of tulips.
A is incorrect because there should be a hyphen between five and dozen: five-dozen eggs because it is a compound adjective. B is incorrect because the word thousands should be singular: seven thousand people/thousands of people (without seven). D is incorrect because the word hundred should be plural: hundreds of quilt.
This leaves us with C as the correct answer.
B. hubris: excessive pride or self-confidence.
