The Mechanism for the Reaction 2H₂O₂(aq) $\rightarrow$ 2H₂O(l) + O₂(g) in the Presence of I^-(aq) Is Proposed

The mechanism for the reaction 2H₂O₂(aq) $\rightarrow$ 2H₂O(l) + O₂(g) in the presence of I^-(aq) is proposed to be:
Step 1: H₂O₂(aq) + I^-(aq) $\rightarrow$ H₂O(l) + OI^-(aq)
Step 2: H₂O₂(aq) + OI^-(aq) $\rightarrow$ H₂O(l) + O₂(g) + I^-(aq)
Which of the following species is an intermediate?

A) I^-
B) H₂O₂
C) H₂O
D) OI^-
E) This mechanism has no intermediates.
