This a combination question .
Out of the 3 strikers and 4 mid-fielders we are supposed to pick , we have Bruce and David so we have to pick 2 strikers and 3 mid-fielders out of 5 strikers and 6 mid-fielders respectively as two are fixed . And 3 defenders out of 7 and 1 goal keeper out of 3 .

we use basic combination .
5C2 * 6C3 * 7C3 * 3C1

So we get C. 21000 ways which is the official answer .

As we have to select 11 members out of 23, and then it is given 2 members are compulsory , we have only 9 members to select from remaining people ,

Remaining team is 2(s) , 3(M), 3(D), 1(GK).

Total members available is 5(s), 6(M), 7(D), 3(GK).

5C2 * 6C3 * 7C3 * 3C1 = 21000

SO OPTION C
