The answer is C. Muscle fiber or Sarcomere.
Yes indeed the answer is true BUT wait hold up a minute, u may ask ''Will this cure me of my disease''? Answer: 50% chance yes and the other 50% chance no because STDS can come from sexual intercourse, oral sex, tongue kissing or French kissing or just putting your saliva or someone else saliva in u or him so this can give u STDs and next thing u know your immune system (its the thing that helps u fight diseases and colds) like for ex u got the flu and your immune system helps u get better and fight that cold. But back to topic the disease, CAN or CAN NOT, overpower your defense system( immune system ) and if this STD disease wins over your immune system, sadly its going to be harder for u to stay alive but yes there are cures but that DOES NOT 100% keep u alive though.
