C
112 of the initial the concentration

D
132 of the initial the concentration
loader

Solution

The correct option is A 164 of the initial the concentration
In a first order reaction, fraction of the substance =12n of the initial the concentration, where n is the number of half lives.
As the half life of the reaction is 10 minutes, in an hour there are 6 half lives. So, the fraction of the substance =126=164
