The answer is B: reduced.

Explanation for each option: A. Heightened - This option is incorrect because a warm-up is meant to gradually prepare the body for more intense activity, not to start at a heightened or increased pace. B. Reduced - This is the correct answer. A warm-up should involve performing a similar activity to the main exercise but at a lower intensity to gradually increase heart rate and muscle temperature. C. Crawling - This option is incorrect because "crawling" implies an extremely slow pace, which may not be effective for a proper warm-up. D. Similar - This option is incorrect because while the activity should be similar, the pace should be reduced to avoid injury and properly prepare the body for the main exercise.
