If (y - 2)(z - 3) + 5(z - 3) = 0, then which of the following must be true? Pick one:
A) y = -4 and z = -3
B) y = -4 or z = -3
C) y = -4 or z = 3
D) y = 1 and z = 2
E) y = 1 or z = -1
by taking out common factor,   (z-3)(y-2+5)=0   (z-3) (y+3) = 0   So by checking options we get ,   Ans - y = -4 or z = 3
<result>C</result>
