Next are:
D. Sensory neurons pass information about the stimulus to other nerve cells.
A. Interneurons receive and process information about the stimulus.C. Motor neurons carry directions from inter neurons to muscle cells.

Answer 2

The correct answer would be B. Sensory neurons sense a stimulus.

Environmental stimuli such as heat, pressure, light et cetera are detected or received by the sensory somatic system or sensory neurons.

The signals are then transported to the central nervous system (brain and spinal cord) for processing.

The central nervous system then sends the response signals to the effector organ through motor neurons.
