Answer
Brief Explanations:
Parallel structure requires that items in a list have the same grammatical form. In the third option, "would present", "would show", and "would ask" are all in the same verb - phrase form with the modal "would". In the first option, "present her plan" (verb - object) and "her presentation" (noun) are not parallel. In the second option, "present her plan" (verb - object), "show her presentation" (verb - object), but "then she might ask" has an extra subject "she" breaking the parallelism. In the fourth option, "present her plan" (verb - object), "that there would be time" (subordinate clause) and "people could ask questions" (independent clause) are not parallel.
Answer:
The architect expected that she would present her plan, would show her presentation, and would ask if there were any questions.
