Correct answer is (b) A - (3), B - (5), C - (1), D - (2), E - (5)

Column I		Column II
A	Mond's process	1	$C r_{2} O_{3} + 2 A l \to A l_{2} O_{3} + 2 C r$
B	Van-Arkel-de-Boer process	2	$T i C l_{4} + M g 1000 - 115 0^{\circ} C T i + 2 M g C l_{2}$
C	Thermite process	3	$N i (CO)_{4} 23 0^{\circ} C N i + 4 CO$
D	Kroll process	4	$2 C u O + C u S \to 3 C u + S O_{2}$
E	Self reduction	v	$Z r l_{4} Δ Z r + 2 l_{2}$
