• A. 700 million years
• B. 4.5 billion years
• C. 3.8 billion years
• D. 300 million years

Answer 1

The correct option is B 4.5 billion years

Our planet is estimated to be around 4.5 billion years old. Considering Earth's age of 4.5 billion years, the formation of the Himalayas can be considered a recent event in the geological timeline. The age measured is of Earth's oldest rocks and oldest crystals which show that the Earth is at least 4.5 billion years in age but do not reveal the exact age of Earth's formation.
