After neurotransmitter molecules travel across the synaptic cleft and bind to receptors on the postsynaptic cell,remaining molecules in the synaptic cleft are removed rapidly.If the molecules were not removed,transmission of information would most likely
A) continue at the same rate.
B) continue and become faster and faster.
C) continue and become stronger and stronger.

If neurotransmitter molecules are not removed from the synaptic cleft, they will continue to bind to receptors, causing the postsynaptic cell to remain activated. This can lead to desensitization or downregulation of receptors, causing the membrane to lose its responsiveness and stop transmitting information effectively.
