Answer:

A. Type I is part of innate, nonspecific immunity, while type II is part of adaptive, specific immunity.

Explanation:

Type I interferons: Are produced early on during infection and are responsible for activation of the innate immune response, e.g Natural Killer cells.

Type II interferons: Are produced as part of the innate immune response and act as a link between innate immune response and activation of the adaptive immune response.

Synapses in the spinal cord activate spinal motor neurons without delay, which is likely the case if the signals go to the brain, the brain doe however receive the sensory input during the reflex action.
