Concept:This question tests the correct choice of an adverb in the idiomatic expression "not quite the way," which is used to describe something that happened differently from what was expected.
Explanation:The sentence tells us that he performed the action, but not in the exact manner that the speaker had in mind.
Option B, "quite," combines with "not" to form the fixed phrase "not quite," meaning "not exactly" or "not completely."
With B, the sentence reads: "He did it, but not quite the way I had expected." This is natural, grammatically correct English.
Option A, "as," is incorrect because "not as the way" is ungrammatical and does not form an acceptable English construction.
Option C, "hardly," already carries a negative sense, so adding it after "not" would produce an illogical double negative.
Option D, "so," is also wrong, because "so" normally modifies an adjective or adverb, and it does not fit before "the way."
Therefore, "quite" is the only word that produces a correct and meaningful sentence.
Answer:B. quite
