The answer would be D I am pretty sure :)
Ok, if this isn't right then I am sorry, but I am pretty sure it is (C) because my sister does dance, and during one of her intensives, her friend fractured her ankle and she came home a couple days ago from dance saying that she has to build up all that muscle all over again because there is no muscle left, it was completely diminished.
Answer: the correct option is C (Use an antiseptic and put on a glove over the infected cut Leave it alone).
Explanation: An antiseptic is antimicrobial substance that are applied to living tissue/skin to reduce the possibility of infection.
Therefore if you have an infected cut on your hand that is swollen and red. You use an antiseptic and put on a glove over the infected cut .
