Final answer:
The four properties of water that sustain life on Earth are its high surface tension, high heat capacity, strong solvent properties, and high heat of vaporization.
Step-by-step explanation:
The list of four properties of water that allow Earth to sustain such abundant life includes: high surface tension, high heat capacity, high solvent properties, and high heat of vaporization. Each of these properties is essential for maintaining the climate, facilitating nutrient transport, and supporting biochemical reactions necessary for life. The correct answer to the student's multiple-choice question is C. High heat capacity, high solvent properties.
