{'cioj': [0, 0, 0, 1], 'cloj': [0, 0, 0, 1], 'capablc': [0, 0, 0, 1], 'cio': [0, 0, 0, 1], 'species': [0, 0, 0, 2]}

The correct answer is option 4: ClOj.

Disproportionation reaction is a type of redox (reduction-oxidation) reaction in which a compound is simultaneously oxidized and reduced, resulting in the formation of two different products. In this reaction, one part of the compound is reduced while another part is oxidized.

In the given options, we have three different species: CIO-, CIO;, and CIOj.

Option 1: CIO- is capable of showing a disproportionation reaction. It can be both oxidized and reduced to form different products.

Option 2: CIO; is also capable of showing a disproportionation reaction. It can undergo both oxidation and reduction to form different products.

Option 3: CIOj is also capable of undergoing a disproportionation reaction. It can be both oxidized and reduced, resulting in the formation of two different products.

Option 4: ClOj is the species that is not capable of showing a disproportionation reaction. It does not have the ability to simultaneously undergo oxidation and reduction.

Therefore, the correct answer is option 4: ClOj.
