B Correct answer
Explanation

Earth's axis is tilted at approximately 23.5 degrees relative to its orbital plane around the sun. This tilt causes the poles to experience continuous daylight or darkness for about six months each year as Earth orbits. When the North Pole tilts toward the sun, it has six months of daylight while the South Pole has six months of darkness.
