Myasthenia gravis is an autoimmune disease in which the immune system produces antibodies that attack the acetylcholine receptor on the motor end plate. What symptoms would you expect with this disease?

In the given question, the options are not provided but from the information in the question the most common symptoms can be deduced which is the the fatigue and weakness in the voluntary muscle.

Explanation:

Myasthenia gravis is an autoimmune disease which is caused when the immune response consider the own cells and tissues as antigens.

The person with Myasthenia gravis produces antibodies which attacks the acetylcholine receptors involved in the motor neuron transmission at motor end plate.

Since the electrical signals are transmitted from the motor neurons to the muscle at motor end plate and when antibodies attacks the receptor therefore it would cause the muscle fatigue or weakness in the voluntarily muscle.

Thus, the fatigue and weakness in the voluntary muscle is correct.
