Think of a plant which lacks chlorophyll. From where will it obtain nutrition? Give an example of such a type of plant.

(N/A) Plants that lack chlorophyll are heterotrophic in nature and cannot perform photosynthesis.
They obtain their nutrition from other sources such as decaying organic matter (saprophytes) or by parasitizing other living plants (parasites).
An example of such a plant is $Monotropa$ (also known as the ghost plant or Indian pipe),which is a myco-heterotroph that obtains nutrients from fungi associated with the roots of other plants.
