(C) The correct option is $C$. $6$.In the structure of sulphuric acid $(H_2SO_4)$,the sulphur atom is bonded to four oxygen atoms.Two oxygen atoms are bonded via double bonds $(S=O)$ and two oxygen atoms are bonded via single bonds $(S-OH)$.Counting the total number of bonds formed by the sulphur atom,we get $2 + 2 + 1 + 1 = 6$ bonds.Therefore,the valency of sulphur in $H_2SO_4$ is $6$.
