Near the end of both march and september a) spring begins in both hemisphere b) the sun's rays strike earth with the same intensity everywhere. c) earths axis is no longer pointing at north star. d) neither end of earths axis is tilted toward the sun.

The correct answer is D. neither end of Earth's axis is tilted toward the sun.

Spring begins at the same time everywhere as a time reference, not as a climate and weather reference. It is also impossible for sun to strike at the same time everywhere since the earth is not a flat disk oriented towards the sun. Earth's axis always points towards the North Star.
