Ohh.. Okay.. Sorry.. Bt I can solve that doubt of yours... When the muscle is relaxed, it uses up 30% oxygen by lowering 90% to 60%... Bt when there's muscle contraction.. more energy is needed so more oxygen will be used up by the muscle... The only option less than 60 is 40... So it has gotta b A...

Yup , you are correct

 

[Shepard97]

It is 30 % , so the closest option is 40 , hence it's A..
this was so EASY -_-
