Solution

The correct option is B 2472

Select 3 bowlers out of 4: (43)
(43)
Select 1 wicket keeper out of 2: (21)
(21)

Select the remaining 4 players out of 12: (127)
(127)

Hence, total permutations (43)(21)(127)=6336

So,

Total no of bowlers=4

Total no of wicket keepers=2

Total required selection=

(43)(21)(107)+(44)(21)(106)+(43)(22)(106)+(44)(22)(105)=2472
