  1. Plantation of $C _3$ plants

  2. Plantation of Sugarcane

  3. Energy plantation

  4. None of the above

Show answer
Correct Option: C
Explanation:
  • Energy plantation is the practice of planting trees, purely for their use as fuel. Terrestrial biomass i.e., the wood plants have been used for a long time to generate fire for cooking and other purposes.
