The answer is; A
This is because this side is tilted towards the sun. Also, if you observe keenly, even when the earth rotates around its tilted axis, this position will still be receiving sunshine throughout the 24 hours. From this position, the sun never sets. However after approximately 6 months, when the sun is on the other side of the earth and the south pole is closer to the sun than the north pole, then point A will be in darkness for 24 hours each day, while position D will be the one receiving 24 hours sunlight.
