The sequence starts with a dendrite (D), which receives signals from a receptor. The signal then travels to the cell body (CB) of the neuron. From there, it continues along the axon (A) until it reaches a synapse (S). At the synapse, the signal is transmitted to another dendrite (D), which belongs to a different neuron. The signal then travels to the cell body (CB) of this second neuron and continues along its axon (A). Therefore, based on option 1, the most likely sequence of structures between a receptor and an efferent is D - CB - A - S - D - CB - A.

Hence, the correct answer is option 1.
