If for a reaction `t_(x//y)` represents time required for `(x)/(y)`th fraction of reactant to react then identify the correct option for a first order reaction :
Statement-I : `t_(3//4)=t_(1//2)xx2`
Statement-II : `t_(15//16)=t_(1//2)xx4`
Statement-II : `t_(7//8)=t_(3//4)xx2`
Statement-IV : `t_(15//16)=t_(3//4)xx3`

Options

A. All statements are correct
B. Only Statement-I is correct
C. Statement-III and Statement-IV are incorrect
D. Statement-II and Statement-IV are correct

Answer
