Three boys T, R and M are sitting in a row facing towards the north (not necessarily in the same order), and three girls F, G and K are sitting in a row facing towards the face of these boys (not necessarily in the same order). F and R are diagonally opposite to each other. K is not at any of the ends.

Which of the following pairs of persons facing towards each other is/are definitely correct?
I. GR
II. KT

Only I

Answer: Only I

In this question we will first place K in the middle and then place F and G at corners in the row facing south. Now we will place R opposite to F which is now facing G.

The places of M and T are not fixed.
