To determine which planets lie between Mars and Uranus based on their distances from the Sun, we need to consider the order of the planets in the solar system. Let`s examine each option and reason through them:

Option 1: Earth and Jupiter

The order of planets from the Sun is: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune. In this option, both Earth and Jupiter are listed. Earth is closer to the Sun than Mars, and Jupiter is farther from the Sun than Uranus. Therefore, this option is incorrect because Jupiter is not between Mars and Uranus.

Option 2: Jupiter and Saturn

Following the same reasoning as above, we find that Jupiter is indeed between Mars and Uranus. Jupiter is the fifth planet from the Sun, located between Mars (the fourth planet) and Saturn (the sixth planet). So, this option is correct.

Option 3: Saturn and Earth

In this option, Earth is listed between Mars and Uranus. However, this is incorrect because Earth is closer to the Sun than Mars. Additionally, Saturn is farther from the Sun than Uranus. Therefore, this option does not meet the criteria of having planets between Mars and Uranus based on their distances from the Sun.

Option 4: Saturn and Neptune

Similarly to the previous explanation, Saturn is farther from the Sun than Uranus, so it cannot be between Mars and Uranus. Additionally, Neptune is located beyond Uranus in the solar system. Hence, this option is incorrect as well.

In conclusion, the only option where the planets lie between Mars and Uranus based on their distances from the Sun is Option 2: Jupiter and Saturn.
