The correct answer is 45-90 degrees, as these angles are appropriate for subcutaneous injections and are dependent on the patient's body mass. For individuals with adequate subcutaneous tissue, a 90-degree angle can be used, especially with shorter needles. In leaner patients, a 45-degree angle is often recommended to avoid intramuscular injection. A 15-degree angle is too shallow and may not place the needle in the subcutaneous tissue, while a 180-degree angle would be parallel to the skin, making injection impossible.
