A) 0
B) $- 1$
C) 4
D) does not exist

As $x$ approaches $-$ from the left side, the expression $4 - 5x$ will become increasingly large because the negative value of $x$ gets multiplied by $-5$, making the product positive and large. Therefore, the limit does not depend on $x$ approaching from the left or right; it simply evaluates to the constant term $4$.
