The correct response is: Constellations that lie near the ecliptic are visible all year.
However, it should be noted that while many constellations near the ecliptic are visible throughout the year, specific visibility can vary depending on the observer's location and time of year. The other statements are inaccurate or misleading. For example, while constellations that lie far from the ecliptic may have different visibility patterns, they are not necessarily "always" visible or "never" visible. Also, constellations are not classified based on their shape (e.g., "elliptical" shapes are not used to describe constellations), and constellations near the ecliptic can indeed be blocked by the Sun during certain times of the year.
