The answer is B 
Hope this helps with your question 

The answer is: B) Lift and stand up slowly, keeping your back straight and letting your legs do the lifting.

Failing to control the speed of your lifting and maintaining proper posture could cause you to suffer from muscle strains. In worse case scenario, muscle strains is not only your problem. Since areas that hurt from lifting accidents could be located around your lumbar, it can even damage your ability to walk.
