B Correct answer
Explanation

We need to select 6 players from 10, but 2 are already included. We only need to choose 4 more players from the remaining 8. The number of ways is 8C4 = (8*7*6*5)/(4*3*2*1) = 70.

AI explanation

Since 2 particular players must be included, we need to select the remaining 4 players from the other 8 players. Using the combination formula, this is calculated as 8C4. The value of 8C4 is (8 times 7 times 6 times 5) divided by (4 times 3 times 2 times 1), which equals 70.
