○ living things would not be able to live, reproduce, or regulate their own temperature.
○ living things would not be able to absorb and transport heat or regulate their own temperature.
○ living things would not be able to reproduce or absorb and transport heat.
○ living things would not be able to regulate their own temperature, live, or absorb or transport heat.

Explanation:

Water is critical for all core biological functions: it is essential for cellular survival (enabling living things to live), is involved in reproductive processes for many organisms, and acts as a key agent for temperature regulation (e.g., sweating in mammals, transpiration in plants). The other options omit one or more of these vital impacts.

Answer:

Living things would not be able to live, reproduce, or regulate their own temperature.
