If we have m resource's of same type and they are shared by 3 process's then
A needs 3 resource's of same type .
B needs 4 resource's of same type .
C needs 6 resource's of same type .
first of all we find out after how many resource's if we give them the system still be in Deadlock.
So
A needs 3 resource's of same type .If we only give 2 resource to A then it will still be in deadlock
B needs 4 resource's of same type .If we only give 3 resource to B then it will still be in deadlock
C needs 6 resource's of same type .If we only give 5 resource to C then it will still be in deadlock
we have given total of 10 resources still the system is in deadlock .To break this deadlock we give them one more.
So Answer :A (11 resources of same type).
