Using the table, the planets with the most similar atmospheres are Saturn and Uranus.
To determine which planets have the most similar atmospheres, we need to compare the percentages of the different gases in each planet's atmospheric composition.
From the table:
- Jupiter's atmospheric composition is 90% hydrogen, 10% helium, and 0.3% methane.
- Saturn's atmospheric composition is 90% hydrogen, 3.5% helium, and 0.5% methane.
- Uranus's atmospheric composition is 83% hydrogen, 15% helium, and 2% methane.
- Neptune's atmospheric composition is 80% hydrogen, 19% helium, and 2% methane.
Comparing the percentages, we can see that Jupiter and Saturn have the most similar atmospheres, with both having high proportions of hydrogen and helium, and relatively low proportions of methane. Therefore, the correct answer is "Jupiter and Saturn."
