Which one of the following statements is correct with reference to our solar system?

The earth is the densest of all the planets in our solar system.

The correct answer is Option (1) - The earth is the densest of all the planets in our solar system.

The earth is the densest of all the planets in our solar system. Earth is the fourth smallest of the planets—though in terms of the rocky planets, it's the largest—but it's the most dense. Jupiter is the largest planet in the solar system, but it's Saturn—the solar system's second-largest planet—that takes the prize for least dense.

The predominant element in the composition of Earth is oxygen and not silicon.

The Sun contains 99 percent (not 75 percent) of the mass of the solar system.

The diameter of the sun is 109 times (not 290 times) that of the Earth.
