Can somebody please answer the coding assignment :) Assume that a, b, and c are variables of type int. Consider the following three conditions.

I.
(a == b) && (a == c) && (b == c)
II.
(a == b) || (a == c) || (b == c)
III.
((a - b) * (a – c) * (b – c)) == 0
Which of the conditions above evaluates to true given that at least two among the variables a, b, and c are equal?

II and III
I only
I and II
III only
