The best way to discover if there is water on the surface of Mars is option A) Send space probes to Mars to study the surface.

Explaining how to get the answer:
To determine if there is water on the surface of Mars, it is necessary to gather direct evidence from Mars itself. This is why the most effective way to investigate the presence of water is by sending space probes to Mars. These probes can carry instruments specifically designed to analyze Martian soil and rock samples to detect any signs of water. Additionally, these probes can study the planet's atmosphere and use remote sensing techniques to search for evidence of water, such as the presence of ice caps or atmospheric humidity. By directly exploring Mars, scientists can gather the most accurate and reliable information about the presence of water on its surface.
