Answer : 4. "पौधे की एक नई प्रजाति"
Explanation :

Thismia malayana, a newly discovered mycoheterotrophic plant in the rainforests of Peninsular Malaysia, steals nutrients from underground fungi rather than photosynthesizing. It thrives in the low-light forest understory, with special flowers pollinated by fungus gnats. Typically 2 cm long, it grows near tree roots or rotten logs and is highly sensitive to environmental changes, earning it vulnerable status on the IUCN Red List.
