'G' may be male/female so option 2 is correct because B, C, D are girls that is final.

Indirectly given that A sits with HIS best friends which means A is a male and D is the only female in the 1st row.

There can be only three girls as we see that the pronoun for A is written as 'his'. So, option A is correct one. If not, you will face another problem in one of the next questions about a group of girls which is having its answer as CBD.

According to me, the solution is;.

Consider this, " A sits on the bench I with his best friends" means A is a boy "E is the brother of C " means E also is a boy. That leaves with only "3" girls - can't be 4 girls.

According to me, The question is in wrong format. It should have been, how many girls can we assume out of 7? Otherwise, the answer is data inadequate.

It can also be 1) AFB, 2) ED, 3) GC.

Answer (b) is correct as we can clearly see there are three girls (d, b, c) definitely but we can't make out G is a girl or a boy. So the answer (b) 3/4 is correct.

The arrangement can be made easily but a number of girls and boys is little tricky.
