Select the equivalent simplified product and all restrictions for the rational-expression product (9r
2
+ 63r - 162)/(10r
3
- 120r
2
+ 440r - 480) * (25r
2
- 75r - 100)/(6r
2
+ 84r + 270).
A
4(r + 5)(r - 6)/(15(r + 1)); restrictions: r != -9, -5, 2, 4, 6
B
15(r + 1)/(4(r + 5)(r - 6)); restrictions: r != -5, 2, 4, 6
C
15(r + 1)/(4(r + 5)(r - 6)); restrictions: r != -9, -5, 2, 4, 6
D
15(r + 9)(r + 1)(r - 2)(r - 4)/(4(r + 9)(r + 5)(r - 2)(r - 4)(r - 6)); restrictions: r != -9, -5, 2, 4, 6
