We are to form the combination of 6 objects taken 2 at a time. This can be expressed as 6C2
![6C2= \frac{6!}{2!*4!} \\ \\ = \frac{6*5}{2} \\ \\ =15](https://tex.z-dn.net/?f=6C2%3D%20%5Cfrac%7B6%21%7D%7B2%21%2A4%21%7D%20%5C%5C%20%20%5C%5C%20%0A%3D%20%5Cfrac%7B6%2A5%7D%7B2%7D%20%5C%5C%20%20%5C%5C%20%0A%3D15%20%20)
This means, there can be 15 different combinations of 2 members that can sit in the front row.
So, the answer to this question is option A
