Match the items of Column $(A)$ with those of Column $(B)$:

Column $(A)$	Column $(B)$
$(a)$ Phloem	$(i)$ Excretion
$(b)$ Nephron	$(ii)$ Translocation of food
$(c)$ Veins	$(iii)$ Clotting of blood
$(d)$ Platelets	$(iv)$ Deoxygenated blood

(A) The correct matches are as follows:
$(a)$ Phloem is responsible for the $(ii)$ Translocation of food in plants.
$(b)$ Nephron is the structural and functional unit of the kidney involved in $(i)$ Excretion.
$(c)$ Veins are blood vessels that carry $(iv)$ Deoxygenated blood towards the heart.
$(d)$ Platelets are blood cells that help in the $(iii)$ Clotting of blood.
Therefore,the correct sequence is $(a-ii, b-i, c-iv, d-iii)$.
