After all, balanced muscle development is needed to maintain a healthy back, since the muscles on opposite sides of the spine must pull equally in opposing directions to keep the back in proper alignment and protect the spine.
Which one of the following is an assumption required by the argument?
(A) Muscles on opposite sides of the spine that are equally well developed will be enough to keep the back in proper alignment.
(B) Exercising the muscles on opposite sides of the spine unequally tends to lead to unbalanced muscle development.
(C) Provided that one exercises the muscles on opposite sides of the spine equally, one will have a generally healthy back.
(D) If the muscles on opposite sides of the spine are exercised unequally, one's back will be irreparably damaged.
(E) One should exercise daily to ensure that the muscles on opposite sides of the spine keep the back in proper alignment.

IMO - B

Conclusion : to maintain a healthy back, it's important to exercise the muscles on opposite sides of the spine equally.
Main Premise : balanced muscle development is necessary to maintain a healthy back.

Our task is to find a connection between equal exercise and balanced development. Choice B does that.

To prove it, lets negate choice B. - "Exercising the muscles on opposite sides of the spine equally tends to lead to unbalanced muscle development. " Now see the it impacted conclusion.

According to me

Conclusion :balanced muscle development is necessary to maintain a healthy back.
Main Premise : muscles on opposite sides of the spine must pull equally in opposing directions to keep the back in proper alignment and protect the spine

We need a link between the the muscles on opposite sides of the spine must pull equally in opposing directions to keep the back in proper alignment and protect the spine and balanced muscle development

The choice B says that clearly
Exercising the muscles on opposite sides of the spine unequally tends to lead to unbalanced muscle development.

or if you negate it, the result is

Exercising the muscles on opposite sides of the spine unequally does not lead to unbalanced muscle development. which breaks the link between the premise and conclusion
