Choose the most appropriate answer from the options given below :

We are given that B sits at the extreme right end of the row.

We are also given that G is second to the left of B and E sits between G and E. 

_ _ _ _ G E B

Only two people sit between G and F. 

_ F _ _ G E B

D sits third to the left of C, the only possible placement is:
