The number of ways to choose and seat the seven students can be found using the formula for permutations, which is n! / (n-r)!, where n is the total number of objects and r is the number of objects being chosen.
In this case, n = 7 (the number of students) and r = 7 (all of the students are being chosen).
So the number of ways they can be chosen and seated is 7! / (7-7)! = 7! / 0! = 7! / 1 = 7! = 7 x 6 x 5 x 4 x 3 x 2 x 1 = 5040.
Therefore, the answer is A. 5040.
