The given sentence is grammatically correct as it stands: The bear, expected to begin hibernation any day now, hunts for food every hour. Here option A is correct.
The sentence effectively communicates the idea that the bear is expected to start hibernating soon and is currently engaged in hunting for food. The verb "hunts" is appropriately used to convey the bear's ongoing activity.
The alternatives provided, (B) "now, hunt," (C) "now, have hunted," and (D) "now hunt," introduce grammatical errors or awkward constructions.
For example, option (B) lacks subject-verb agreement, (C) uses the past perfect tense ("have hunted") inappropriately, and (D) removes the connecting verb "to begin," resulting in an incomplete and awkward structure. Here option A is correct.
