Explanation:

Recently the plant has caused the ‘pink phenomenon’ in Kerala by covering the water bodies.

Cabomba Furcata

• Cabomba is a submerged perennial aquatic plant that grows in stagnant to slow-flowing freshwater.
• It dominantly belongs to Central and South America.
• The plant will spread in the water bodies across, choking them as well as the drainage canals.
• It requires a huge amount of oxygen to grow and that could badly affect freshwater biodiversity.
• The plant has a high natural dispersal potential due to its ability to readily fragment and spread.

Hence only statement 1st is correct.
