Answer: D - The best choice is “gained control, it implemented plans”

In the original sentence, the past tense verb “continued” and the present tense verb “implements” creates faulty parallelism. The verbs in the sentence should have the same tense. Since an event - the election of Mohamed Morsi - occurred after the Supreme Council took control, the verbs in the first sentence should convey something that happened in the past. “Implemented” is the past tense form of “implement.”
