The auroras occur in the
a. troposphere
c. mesophere
b. stratosphere
d. ionosphere

d. ionosphere

Explanation:

The auroras are caused by the sun, the energy and particles that reach us from the sun are trapped in the earth's magnetic field, which causes the auroras that we see in the Earth's poles.

The auroras are produced in the layer called ionosphere, here there are gases that interact with the particles of the solar wind trapped in the magnetc field, the different colors of auroras such as red, green, blue or violet are the result of the different gases that exist in the ionosphere.
