The correct answer is D. Practicing and drills
Explanation:
Sports injuries are often the result of exercising or practicing a sport inappropriately, this includes overs use and overexertion that are the result of repetitive movement or trauma, and incorrect techniques that can lead to traumas as muscles, tendons, etc. move or stretch excessively or improperly. However, practicing and drills are not part of the dangerous conditions that influence or cause sports injuries because if these are done appropriately they lead to improvement rather than to possible traumas as they involve different tasks that help individuals to improve ability, strength, etc.
