4 Different integers, least product required.

Choose the 3 largest absolute positive values and smallest negative value
P = 10*9*8*(-5) = -3600 :)

B is correct

I have a question. Why can the answer not be E -120. Are we not looking for the least value. -120= 3*4*2-(-5)?

-3600 is smaller than -120. (LEAST means the smallest value) :)
