Is there any reason why row 8 on this aircraft cost £5 more than the rest to select seats in?

Both BA 761 and 768 on 12 and 22 september gives me the ability to book seats in DEF in row 8, but they are higher priced than any other seats except exit rows. Seats ABC are not available on either flight. Are these special seats of some sort?

I'm not paying to select seats for such short flights, but it would be good to know in case they are available at checkin. I usually go for the first available A seat.
