(A) is missing the seriousness of theme — where’s the message in the work? Also, it’s not clear that (A) is an example of pop art. Although (A) involves “realistic techniques,” that’s not the same as “commercial-art techniques.” (A) is more like a still-life painting (look it up if you don’t know what it is).

(B) is missing the “more than just parody” aspect of Lichtenstein’s work.

There’s no suggestion that Lichtenstein was trying to convey any “inner turmoil.” Although Lichtenstein’s work had emotion, that doesn’t imply the creator experienced inner turmoil. Also, it’s not clear that (C) is pop art — where’s the commercial-art aspect of the painting?

It’s not clear that (C) is pop art — where’s the commercial-art aspect of the painting? “Vague shapes and images” doesn’t suggest that there are commercial-art aspects to the painting.

This is the best answer. It’s pop-art, because it involves commercial-art aspects (showing products as they appear in magazine advertisements, similar to how Lichtenstein paraphrased the style of comic books). In addition, (E) captures the seriousness of theme — the work has a message and is trying to say something about the world, just as Lichtenstein was. (He wanted to bring back realism, depictions of contemporary life, nostalgia). Sometimes people have a problem with “comment on society’s values” in (E). Although Lichtenstein wasn’t cynical about consumer culture, this doesn’t imply that he didn’t comment on society’s values.
