Ravina was very sick today, and we will take her to the hospital as she gets worse.

Correct option is B

(b) we will take her to the hospital now before she gets worse: This option effectively addresses the need for immediacy and preventive action given Ravina’s condition. The phrase "now before she gets worse" logically implies that taking action (going to the hospital) is urgent to prevent her condition from deteriorating further. This option uses the correct future tense ("will take") consistent with the planned action, and it properly aligns with the seriousness of her being "very sick today."
Why Other Options Are Incorrect:
· (a) we took her to the hospital now before she gets worse: This choice incorrectly uses the past tense "took," which does not agree with the future-oriented action described in the sentence. It suggests the action has already been completed, which conflicts with the urgency and forward-looking context indicated by "now before she gets worse."
· (c) No substitution: The original phrase "as she gets worse" suggests a condition for action that is continuously deteriorating, which doesn’t prompt immediate action as needed in the context.
· (d) we can take her to the hospital now before she get worse: This choice has a grammatical error in the verb agreement ("she get" should be "she gets"), and the modal verb "can" implies possibility rather than the certainty and urgency required by the context.
