20 g of non-electrolyte, non-volatile solute `(C_(x)H_(2x)O_(6))` when dissolved in 100 gm water at `100^(@)C`, lowers the vapour pressure of solution by `(1)/(100)`th of the vapour pressure of pure water at this temperature. What is formula of the compound ?

`C_(6)H_(12)O_(6)`

`C_(12)H_(24)O_(12)`

`C_(44)H_(88)O_(44)`

`C_(3)H_(6)O_(3)`
