To find the number of ways seven students can line up for a picture, you need to calculate the factorial of the number of students.
Factorial represents the product of an integer and all the positive integers below it. It is denoted by the exclamation mark (!). For example, 7! (read as "7 factorial") is calculated as:
7! = 7 x 6 x 5 x 4 x 3 x 2 x 1 = 5,040
Therefore, there are 5,040 ways seven students can line up for a picture. So, the correct answer is 5,040.
