Ans is option b
Explanation-
First check on which point is the fumction log x is 0
It will come as 1 . Hence at 1 the function is discontinuous and the imtegral will break im twoo parts-
1) solve the function with limit from 1/2 to 1 . Also whithin this range mod is negative so multiply -1 amd open the mod and solve.
2) solve the function with limit from 1 to 2 . The function is positive in this range so remove the mod and write the function as it is and solve the integral.
Now combine the answeres of 1 an 2 an rearrange using log properties. The answer will come as option b.
 
Sorry for any grammatical mistake
