Answer: Mars receives more insolation than Saturn.
Step-by-step explanation:
Insolation is defined as the exposure to the Sun's rays.
Mars is the 4th planet in Our solar system and is near to the Sun.
Saturn is the 6th-planet in Our solar system and is far from the Sun.
Insolation is directly proportional to the planet's distance from the Sun.
So, the exposure of Sun's rays is more to the planet which lie close to the Sun.
As, Mars is close to the sun than Saturn. Hence, it will receive more insolation than Saturn.
