In general, the kinetic energy of water molecules in a sample is directly related to the temperature of that sample. The lower the temperature, the lower the kinetic energy of the molecules.
If you refer to the table and identify the temperature of each water sample (which appears to be absent in your message), the sample with the lowest temperature will have the lowest kinetic energy.
Please check the table and identify the sample with the lowest temperature to determine which one has the lowest kinetic energy. If you provide the temperature values associated with samples 1, 2, 3, and 4, I can help you identify the correct answer.
