The oxidation state of Cr in CrO5 is +6.

Here's how you can determine this:

1. Oxygen usually has an oxidation state of -2.

2. In CrO5, there are five oxygen atoms, so the total oxidation state for all oxygen atoms is -2 * 5 = -10.

3. The sum of the oxidation states in a neutral compound is zero.

4. Therefore, the oxidation state of Cr in CrO5 is +6 because +6 + (-10) = 0.

So, the correct answer is (a) +6.
