Final answer:
The constellation that is at the same location as the Sun in the sky is part of the zodiac and is visible at a different time of year when it is not obscured by the Sun's light.
Step-by-step explanation:
If the Sun and a constellation are at the same location in your local sky, then that constellation is not visible at night since it is obscured by the Sun's brightness. However, the importance of the question lies in understanding the ecliptic and the zodiac constellations. The ecliptic is the path the Sun appears to follow over the course of a year due to Earth's orbit around it.
This path is not random but rather moves through a specific set of constellations known as the zodiac. The Sun spends about a month in each of these zodiac constellations. Consequently, during that month, the given zodiac constellation cannot be observed as it is too close to the Sun's bright light. So the answer to the student's question is E. Both C & D, visible at a different time of year, and part of the zodiac.
