Answer:
The correct answer is option D. "1,200 years".
Step-by-step explanation:
The giant sequoia (Sequoiadendron giganteum) are the most massive trees in the world, and the tallest is one sequoia called "General Sherman" with a height of 83.8 m. "General Sherman" is estimated to be 2,000 years old, and is estimated that a sequoia tree can live up to 3,500 years. Therefore, an 80-meter sequoia tree in the forest most likely will have more than 1,000 years.
