The winter solstice in Vancouver occurs on December 21st or 22nd. At this latitude (49° North), the Sun will reach its lowest point in the sky, which is also the shortest day of the year. The maximum height above the Southern horizon for the Sun on this day will be equal to the angle between the horizon and the Sun at its highest point. This angle can be calculated using the formula: 90° - latitude + (axial tilt of Earth). Plugging in the values, we get: 90° - 49° + 23.5° = 64.5°. However, the question asks for the maximum height above the Southern horizon, which is the complement of this angle (90° - 64.5° = 25.5°). But since the Sun is in the Northern hemisphere during winter solstice, it will not reach a height above the Southern horizon. Instead, it will reach its lowest point in the Northern sky, which is approximately 17.5° above the horizon. Therefore, the best choice is B.
