B. Adduction is the movement of a body part toward the midline of the body, opposite of what the question describes.
C. Extension refers to a straightening movement that increases the angle between two body parts, such as straightening the arm or leg, but again does not involve lateral movement.

Correct Answer is A
Explanation
A. Type AB positive blood is the universal recipient because individuals with this blood type can receive blood from all other blood types (A, B, AB, and O) due to the presence of both A and B antigens on their red blood cells, and the Rh factor being positive allows them to accept Rh-positive or Rh-negative blood.
B. Type O negative blood is the universal donor, not the recipient. It can be given to any patient, but those with O negative blood can only receive from other O negative donors.
C. Type B negative can only receive blood from B negative or O negative blood types, limiting its compatibility with other blood types.
D. Type A positive individuals can receive blood from type A, type O, type B, and AB, but not as universally as AB positive, which is the universal recipient.
Correct Answer is B
Explanation
A. Vitamin B12 is not synthesized in the skin. It is primarily absorbed through the digestive system from dietary sources such as meat and dairy products.
B. Vitamin D is synthesized in the skin when exposed to sunlight, specifically ultraviolet B (UVB) radiation, which triggers the production of vitamin D3, a precursor to the active form of vitamin D.
C. Vitamin A is obtained from dietary sources, such as fruits and vegetables, and is not synthesized in the skin.
D. Vitamin K is primarily absorbed from food and produced by bacteria in the intestines, not synthesized in the skin.
