Answer 1

The Correct Option is A

The planet Mars is known as the "Red Planet" due to its reddish appearance, which is visible even from Earth. This distinctive color is caused by the presence of iron oxide (commonly known as rust) on its surface. Here's why the other options are incorrect:
- Option (1): Mars: This is the correct answer, as Mars has a reddish hue due to the iron oxide in its soil and rocks.
- Option (2): Mercury: Mercury is the smallest planet in our solar system and does not have a red appearance. It is known for being extremely hot due to its proximity to the Sun.
- Option (3): Venus: Venus is often referred to as the "Evening Star" or "Morning Star" because it is the brightest planet in the night sky. Its surface is covered in thick clouds of sulfuric acid, giving it a yellowish-white appearance.
- Option (4): Saturn: Saturn is famous for its prominent ring system and is not known for a red appearance. It has a pale yellow hue due to its composition of hydrogen and helium. Answer: $\boxed{\text{Mars}}$
