Match Column I with Column II and select the correct answer from given codes.

	Column I (Types of redox reactions)		Column II (Redox reactions)
A.	Combustion reaction	1.	${\mathrm{CH}}_4\left(\mathrm{g}\right)+2{\mathrm{O}}_2\stackrel{\mathrm{\Delta }}{⟶} {\mathrm{CO}}_2\left(\mathrm{g}\right)+2{\mathrm{H}}_2\mathrm{O}\left(\mathrm{l}\right)$
B.	Disproportionation reaction	2.	$2\mathrm{NaH}\left(\mathrm{s}\right)\stackrel{\mathrm{\Delta }}{⟶}2\mathrm{Na}\left(\mathrm{s}\right)+{\mathrm{H}}_2\left(\mathrm{g}\right)$
C.	Decomposition reaction	3.	${\mathrm{S}}_8\left(\mathrm{s}\right)+12{\mathrm{OH}}^{-}\left(\mathrm{aq}\right)⟶ 4{ \mathrm{S}}^{2-}\left(\mathrm{aq}\right)+2{ \mathrm{S}}_2{\mathrm{O}}_3{}^{2-}(\mathrm{aq})+6{\mathrm{H}}_2\mathrm{O}(\mathrm{l})$
D.	Displacement reaction	4.	${\mathrm{Cr}}_2{\mathrm{O}}_3\left(\mathrm{s}\right)+2\mathrm{Al}\left(\mathrm{s}\right)\stackrel{\mathrm{\Delta }}{⟶} {\mathrm{Al}}_2{\mathrm{O}}_3\left(\mathrm{s}\right)+2\mathrm{Cr}\left(\mathrm{s}\right)$
