B)Nothing would change, it would just take longer.

If the receptor labeled B was blocked, ACh would not be able to bind to it and therefore no contraction would occur. ACh cannot bind to any other type of receptor in this specific scenario, as only one receptor is labeled. Therefore, blocking this receptor would effectively prevent muscle contraction.
