The correct answer will be "the loss of ability to contract the muscle".

If a certain toxin blocks the release of neurotransmitters into a neuromuscular synapse, then the neurotransmitter will not be able to work its function to the synapse. For instance, if acetylcholine release is blocked in the presynaptic neuron, then there will be less acetylcholine concentration in the neuromuscular junction, leading to less voltage gated sodium ions open and the muscle less depolarized therefore leading to the loss of ability to contract the muscle.

Answer from: 23basu3

If a toxin released by bacteria can block the release of neurotransmitters into a neuromuscular synapse the result from such a block would be (C) the loss of ability to contract the muscle.

Further Explanation:

Neurotransmitters are the major part of a reaction process. The nerve endings release a chemical substance which is responsible for carrying the nerve impulse from a neuron to another. The minute gap present between the two nerve cells is known as a synapse. If neurotransmitters are not present in the synapse, there would be no transmission of neural signals. No transmission of neural signals would result in incomplete reaction process. For example, if the release of a neurotransmitter known as acetylcholine is blocked, the concentration of acetylcholine would decrease in the synapse. Leading to depolarization of muscles. This depolarization of muscles leads to loss of movement in muscles.

Thus, loss of the contraction ability of the muscles occurs if the bacteria releases a toxin which can block the neurotransmitters release.

Based on the observation that only male crickets produce a song, you hypothesize that a male's song is a form of communication to potential mates. you set up a simple experiment to test this hypothesis. in the laboratory, you place a male snowy tree cricket in enclosure a, which is adjacent to enclosureb. in enclosure b, you place other insects, one at a time, and observe their responses to the male's song. the enclosures are designed so that the two insects being tested cannot see or smell each other, but sound is transmitted from enclosure a to enclosureb.
