Which of the following is the fastest growing tree?

Tree growth rates vary significantly depending on species, climate, and soil conditions. However, some species are renowned for their rapid growth.

• Eucalyptus (B) is correct. Many species of Eucalyptus, particularly those grown in suitable climates, are known for their exceptionally fast growth rates, often reaching impressive heights in a short period. They are widely cultivated for timber, pulp, and essential oils due to this characteristic.
• Teak (A) is incorrect; while valuable, teak is a moderately fast-growing tree, but not as fast as Eucalyptus.
• Sal (C) is incorrect; Sal is a slow to moderately growing tree, prized for its durable timber.
• Banyan (D) is incorrect; Banyan trees are known for their massive size and extensive root systems, but they are generally slow-growing.
