Answer:
The correct answer would be efferent neurons.
Efferent neurons are the motor neurons which communicate information in the opposite direction as compared to the afferent neurons, that is, they communicate information or response impulses from the brain or central nervous system to the muscles or glands.
The response impulses results in the movement of the muscles or activation/deactivation of certain gland
In contrast, afferent neurons are the sensory neurons which carry impulses from the receptors to the central nervous system.

Answer:
The correct answer is option E (testosterone).
Explanation:
The interstitial cells or Leydig cells are the individual or group of cells present in loose connective tissues surrounding the seminiferous tubules. 
They are usually active in the production of dominant sex hormones in males that is testosterone responsible for male secondary sexual characteristics.They produce hormones in the presence of luteinizing hormone (LH) and growth hormone released by the pituitary gland.
