A. 6
B. 40
C. 210
D. 5,040
E. 151,200
Number of options for the first book = 10. (Any of the 10 books.)
Number of options for the second book = 9. (Any of the 9 remaining books.)
Number of options for the third book = 8. (Any of the 8 remaining books.)
Number of options for the fourth book = 7. (Any of the 7 remaining books.)
To combine these options, we multiply:
10*9*8*7 = 5040.
The correct answer is
D.
