Ok, here is the problem.

Let A,B and C be three points in a plane such that AB:BC = 3:5. Which of the following can be the ratio AB:AC ?

I : 1:2

II : 1:3

III : 3:8

Your choices for the answer are:

(A) I only

(B) II only

(C) III only

(D) I and III only

(E) I, II and III

I tried it and my answer was (C). But unfortunately that's not the correct answer. So, someone please help me with this.
