{'isohaline': [0, 0, 1, 0], 'imaginary line': [2, 0, 2, 1], 'radiation': [0, 0, 1, 0], 'insolation': [4, 0, 1, 4], 'sunshine': [2, 0, 1, 0]}
The correct answer is option 3: salinity. An isohaline is an imaginary line that joins places on a map with equal salinity. Salinity refers to the concentration of salt in water.
Option 1: Radiation refers to the emission of energy as electromagnetic waves or as moving subatomic particles. It is not related to the concept of isohaline.
Option 2: Insolation refers to the amount of solar radiation reaching the Earth`s surface. It is not related to the concept of isohaline.
Option 4: Sunshine refers to the direct or indirect sunlight that reaches the Earth`s surface. It is not related to the concept of isohaline.
Therefore, the correct answer is option 3: salinity, as an isohaline is a line that connects places with equal salinity.
