$I.$ shell
$II.$ bones
$III.$ teeth
Choose the correct option

Study the following columns and choose the correct match.

Column-$I$	Column-$II$
$(A)$ Photolysis of water	$(1)$ Zinc
$(B)$ Diazotrophy	$(2)$ Copper
$(C)$ Cytochrome-c oxidase	$(3)$ Manganese
$(D)$ Biosynthesis of $IAA$	$(4)$ Molybdenum
	$(5)$ Boron

Given below are two statements:
Statement $I$: Diazotrophs are the nitrogen-fixing microorganisms,which are exclusively symbiotic.
Statement $II$: Organic fertilizers include farmyard manure,compost,and green manure.
In light of the above statements,choose the most appropriate answer from the options given below.

Match the following columns correctly:

Column $I$	Column $II$
$(a)$ Boron	$(p)$ For $CO_2$ transport
$(b)$ Copper	$(q)$ Essential for nitrogen fixation
$(c)$ Molybdenum	$(r)$ Essential for sugar translocation in plants
$(d)$ Chlorine	$(s)$ Essential for chlorophyll synthesis in plants

Match the physiological processes given in Column-$I$ with the mineral elements given in Column-$II$:

Column-$I$	Column-$II$
$1$. Muscle contraction	$a$. $Mg^{+2}$
$2$. Digestion of food	$b$. $Ca^{+2}$
$3$. Energy exchange	$c$. $Mo$
$4$. Carbohydrate synthesis	$d$. $(PO_4)^{-3}$
$5$. Nitrogen fixation	$e$. $Cl^-$

In which of the following conditions,plants cannot be grown?
