Choose the best alternative for the underlined part 3.
A. NO CHANGE B. but had a decision C. deciding D. yet decided
The best answer is A, because the use of the verb decided results in a clear, complete, and logical sentence. The other choices contain defects in sentence structure. Choices B and D each add a coordinating conjunction (but and yet, respectively) that distorts the meaning of the sentence and creates faulty subordination.
Choice C creates a sentence fragment, because using the present participle deciding (instead of decided) deprives the sentence of a predicate.
