for the least value let's take $f$ as tends to $2$ and $g$ as tends to $-9$.so the least possible value of $fg$is tends to $-18$.let's do the same with the highest value.

the range is$-18<fg<-3$

the range is$-18<fg<-3$

if f=3 and g=-9 then -27<fg<-3

-27<fg<-2..should be.

Can anyone confirm which one is the correct answer?

The correct answer is $-27 < fg < -2$

Just look out for what the highest and least value of $fg$ can be.
