Problem in the both question is that i think they are having two options correct but they are of jee main so how can they be multicorrect
Option 1 is correct. If you examine the equation carefully you will find that B × D is a dimension less quantity because log is on pure numbers. This way A×D has dimensions of C.Now if try this conclusion on every option you will find that A2 has the same dimension as (BC)2. So, option 1 is the correct answer.
