Kinetic energy of the molecules in a substance is directly related to its temperature. The lower the temperature, the lower the kinetic energy.
If you are comparing the temperatures of the water samples from the given table, the sample with the lowest temperature will have the lowest kinetic energy.
Without the specific temperature values, I can't tell you which sample has the lowest kinetic energy. However, you should select the sample with the lowest recorded temperature from the options provided (1, 2, 3, or 4). If you have the actual temperature data, look for the sample with the lowest number.
