(B) $H_2SO_5$ is Peroxymonosulfuric acid (Caro's acid).It contains one peroxide linkage $(-O-O-)$.Let the oxidation number of sulfur be $x$.The oxidation number of $H$ is $+1$,and for oxygen,there are three atoms with $-2$ and two atoms in the peroxide linkage with $-1$.$(2 	imes (+1)) + x + (3 	imes (-2)) + (2 	imes (-1)) = 0$$2 + x - 6 - 2 = 0$$x - 6 = 0$$x = +6$
