The correct option is D analogy
Pygmalion wishes for his beautiful marble statue, Galatea, to come to life and the goddess Aphrodite grants this wish. Here, Mr. Keeble says that this "Pygmalion and Galatea business working the wrong way around"- he says this with respect to his wife who turns very rigid at what Mr. Keeble says. This comparison is drawn out to make Mrs. Keeble's cold nature clear to the audience. So, this comparison involves analogy (which is a comparison between one thing and another, typically for the purpose of explanation or clarification). So, the answer is option D.
