Since any of the two statements are enough to solve the question the other one will be redundant providing same results. So for any combination one of them will be redundant.

Varinder said:   10 years ago
Oh yes. If the redundant statement is asked.

The option D is absolutely right.

Read question carefully. "Whether any information provided in the statement (s) is 'redundant' and can be 'dispensed' with while answering the given question".

i.e. When we find answer using I and II; III is of no use means III is redundant i.e. we can dispense it.

Similarly, there are two more cases in which we can dispense I and II also I. We can dispense I or II or III.
