Select one:
a. 0.61 years
b. 0.76 years
c. 1.24 years
d. 1.39 years

Answer 1

b. 0.76 years

Step-by-step explanation:

Mercury is the closest planet to the Sun and the Earth is the third planet from the Sun.

The orbital period of the Earth is 1 year.

Orbital period of the Mercury is 88 days = 0.24 years (Earth years)

Thus, the difference between the orbital periods of Mercury and Earth is

1 year - 0.24 years = 0.76 years

Thus, the correct option is b.
