Answer:
The correct answer would be Y-chromosome analysis.
Y-chromosome analysis is technique used to search the parental line of a boy on his father's side.
Gender of a person is determined by 
chromosome in humans. XX is present in females and XY is present in males.
Mother always passes X chromosome to her progeny but father passes both X and Y chromosomes. If X is passed from the father then the offspring will be a girl and if Y is passed from the father then the offspring will be the son.
The sons (F₂) of this son (F₁) will also bear the same Y chromosome as that of grand father (P).
Thus, Y chromosome always passes from father to son and hence, Y-chromosome analysis can help in identification of father of this young boy.

Answer: Mars receives more insolation than Saturn.
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.
