OFFICIAL EXPLANATION
B
Comparing the two openings in the choices, "had expected" is correct. The emissions increased in the last year (in the past), while analysts made their prediction before that time in the past. Therefore, we need the past perfect tense: "had expected". Choice (A) or (B) must be correct.
The first difference between (A) and (B) is the missing "them to" in (B). The sentence is still clear without those two words, so not only is (B) possibly correct, it is more likely to be correct than (A), as the GMAT prefers efficiency. The second difference is the word "that" in (B), while "that" is not in (A). There's a "that" earlier in the sentence: "The study showed that" [one thing] "and that" [another thing]. This is a shorter version of saying, "The study showed that. . . and the study showed that. . ." Since the two things are somewhat unrelated, it is proper to include the "that" before the second thing the study showed. (B) is correct.
