When the Northern Hemisphere has the autumnal equinox, the Southern Hemisphere has the vernal equinox. The equinoxes mark the start of different seasons in each hemisphere.

Since the Northern and Southern Hemispheres have opposite seasons. When the Northern Hemisphere has winter - spring - summer - fall starting in January, the Southern Hemisphere has summer - fall - winter - spring.

In the Northern Hemisphere, the summer solstice is when the sun is highest in the sky. This is due to the tilt of the Earth's axis.

Answer:

a. the vernal equinox
