any value multiplied with the whole function completely then it's value remain unchanged (mtlb agr kisi bhi value ko complete function se multiply karo to function unchanged rehta h) ... i. e. A= f+g D= i( f+g) here iota is multiplied by the whole fuction hence it remains unchanged therefore A and D are same. on the other hand B = f + ig iota is not multiplied by whole fuction here , it is only multiplied by g hence not same similar is the case with C
