Vedclass · Answer

(D) Xenogamy is a type of cross-pollination where pollen grains are transferred from the anther of one flower to the stigma of another flower on a different plant of the same species.This process requires external agents for the transfer of pollen grains.These agents can be classified into two main categories:$1$. Abiotic agencies: These include non-living factors like wind $(Anemophily)$ and water $(Hydrophily)$.$2$. Biotic agencies: These include living organisms such as insects $(Entomophily)$,birds $(Ornithophily)$,bats $(Chiropterophily)$,etc.Since both abiotic and biotic agencies can facilitate cross-pollination,both $I$ and $II$ are correct. $III$ is incorrect because insects are only one type of biotic agent,not the only agents responsible for cross-pollination.Therefore,the correct option is $D$ ($I$ and $II$).

Column $I$	Column $II$
$(a)$ Anemophily	$(1)$ By water
$(b)$ Hydrophily	$(2)$ By wind
$(c)$ Zoophily	$(3)$ By insects
$(d)$ Entomophily	$(4)$ By animals
