We have:
3 - knee
4 - hip
5 – shoulder
In total 12And we have 10 empty places
We can choose any 5 for shoulder operations. After that, out of 5 remaining places we can choose any 4 for hip operation. And we have one lest for knee operation

n = 10 C 5 × 5 C 4 × 1 C 1 = 1260
Thus, the option (b) is correct
