The current theory about earthquakes contains an unsolved mystery. What’s the mystery? The theory predicts that earthquakes should generate a lot of heat, but no earthquake-related temperature increases have been observed.

The author’s conclusion is that the current theory leaves at least one aspect of earthquakes mysterious, in that the theory’s predictions don’t match the data: “at least one thing remains mysterious on this theory.”

This is a premise. It supports the conclusion that the current theory is incomplete. (A) is not supported by anything else in the stimulus.

This is a good restatement of the conclusion. The author concludes that the theory leaves something “mysterious,” meaning it doesn’t fully explain observed data. The discussion of temperature data expectation supports this.

This isn’t stated in the argument. The author never claims that earthquakes are impossible to understand, only that the current theory isn’t 100% complete.

We don’t know whether earthquakes are generating heat or not. The author only tells us that 1) according to the current theory, earthquakes will generate heat, 2) we have not observed that earthquake-related heat. The author doesn’t address whether this heat is being produced or not.

This isn’t stated in the argument. The author never claims that the theory is incorrect. She’s merely saying that it needs improvement to account for earthquake data (or lack of it).
