Let R be a commutative ring, a, b e R and ab is a zero-divisor. Show that either a or b is a zero-divisor. We start the proof by (ab) e = 0, c+0. Which of the following is a true statement in the proof? If ac = 0 then a = 0 0 If ac + 0 then b = 0 If ac = 0 then a is a zero divisor If bc = 0 then a = 0

![Let R be a commutative ring, a, b e R and ab is a zero-divisor. Show that either a or b is a zero-divisor.
We start the proof by
(ab) e = 0, e# 0.
Which of the following is a true statement in the proof?
If ac = 0 then a = 0
If ac + 0 then b = 0
If ac = 0 then a is a zero divisor
