Respuesta :

i would say (B) because the other ones a answers that are extream 
The answer would be the first option A) because feeling uncomfortable during exercise means that you need to work out more so you don't feel uncomfortable anymore and even during exercise if you feel uncomfortable, that DOES NOT mean something is wrong with you or your heart, it just means you need to work out more so your body can get use to this.
