Let's solve this step-by-step:
1. Identify the number of moons for inner planets:
- Earth has 1 moon.
- Mars has 2 moons.
Therefore, the total number of moons for the inner planets (Earth and Mars) is:
[tex]\[
1 + 2 = 3 \text{ moons}
\][/tex]
2. Identify the number of moons for outer planets based on the relevant astronomical data:
- Jupiter has 79 moons.
- Saturn has 82 moons.
- Uranus has 27 moons.
- Neptune has 14 moons.
Therefore, the total number of moons for the outer planets is:
[tex]\[
79 + 82 + 27 + 14 = 202 \text{ moons}
\][/tex]
3. Calculate the difference in the number of moons between the outer and inner planets:
[tex]\[
202 \text{ moons (outer planets)} - 3 \text{ moons (inner planets)} = 199 \text{ moons}
\][/tex]
4. Compare the calculated difference to the given options:
- 50
- 90
- 160
- 190
The closest value to the calculated difference of 199 moons is 190.
Therefore, the correct answer is:
[tex]\[
\boxed{190}
\][/tex]
