Answer:
Option (1)
Step-by-step explanation:
Minus notation of the elevations from the sea level represents the distance below the sea level and positive notation represents the elevations above the sea level.
+7 → 7 meters above the sea level
-3 → 3 meters below the sea level
→ 0.5 meters above the sea level
-0.8 → 0.8 meters below the sea level
+0.8 → 0.8 meters above the sea level
→ 0.1 meters below the sea level
-2 → 2 meters below the sea level
Therefore, +7 meters above the sea level will be the farthest point from the sea level.
