Answer:

B. 55

Step-by-step explanation:

Use synthetic division

-3  |  3  17  -16  -65

           -9  -24  120

________________

       3  -8   -40  55

bring down 3 then multiply to -3 to get -9.

add 17 and -9 to get -8.

-8 multiply to -3 to get -24 then add -24 to -16 to get -40 then just repeat the process.
