Answer:
Option C 
Step-by-step explanation:
step 1
Find the slope of AB
we have
A(-3,-1) and B(4,4)
The slope m is equal to


step 2
Find the slope of BC
we know that
If two lines are perpendicular, then the product of their slopes is equal to -1
so

we have

substitute


step 3
Find the equation of the line into slope point form

we have


substitute

Multiply by 5 both sides



Multiply by -1 both sides
