Symptoms of burning, itching, and pain occur when ddt is absorbed through the skin because: motor neurons are depolarized. motor neurons are hyperpolarized. sensory neurons are depolarized. sensory neurons are hyperpolarized.

Option (3)- sensory neurons are depolarized.

Explanation:

Cell membrane potential is known as the difference in the cell potential inside and outside of the cell. This membrane potential helps in the transmission of nerve impulse.

DDT when absorbed in the body causes burning, itching in the body. These sensations are felt by the body due to depolarization. As the nerve impulse shows transmission, the cell potential changes from the resting membrane potential to the polarization phase.

Thus, the correct answer is option (3).
