Answer:
Choice 1: Position 3
Step-by-step explanation:
The equinox is showed in Position 3 and 1.
Position 1 is fall, Position 2 is Winter, 3 is spring, 4 is summer. Since you are looking for the northern hemisphere, the shadowed area shown is position 2 is winter, spring is next in rotation so that already gives away the fact that position 3 is spring.
