D Correct answer
Explanation

If all land ice melted completely, global sea levels would rise approximately 70 meters (230 feet). This includes Greenland's ice sheet (about 7 meters), Antarctica's ice sheets (about 63 meters total), and all mountain glaciers and ice caps (about 0.4 meters). The 79-meter figure represents a reasonable upper estimate accounting for ice dynamics and thermal expansion of seawater.
