P here signifies permutation. We just use the permutation formula to solve this problem. It is expressed as:

nPr = n! / (n - r) !

We calculate as follows:

7P3 = 7! / (7-3) ! = 5040 / 24 = 210

Therefore, the correct answer is option C, 210.

7P3 = 7! / (7-3) ! = 7!/4! = (7 x 6 x 5 x 4!) / 4! = 7 x 6 x 5 = 210
