Step-by-step explanation:
The correct answer is option C, which states that DA Form 3349 is used to record permanent profiles and temporary profiles in excess of 7 days. DA Form 3349, officially titled 'Physical Profile,' is utilized by the United States Army to document the medical condition of soldiers and detail any limitations on their physical abilities.
When a soldier has an illness, injury, or medical condition that limits their physical capabilities for a significant duration, this form provides the necessary documentation and guidance about their ability to participate in various physical activities, including military training and operational duties. This form becomes a crucial part of a soldier's medical records, ensuring that their medical status is clearly communicated and appropriate accommodations or adjustments can be made regarding their service requirements.
