Answer:
A. The catalytic activity of the complex is enhanced by the protein component and completely dependent on the RNA component of the complex.
Explanation:
RNAses are enzymes that degrade RNA. When treating the complex with an RNAse, the catalytic activity is completely abolished. This tells us that the RNA component is indispensable to the catalytic activity of the complex.
Proteases are enzymes that degrade proteins. Treating the complex with proteases only decreases slightly the catalytic activity, but it does not abolish it completely. This tells us that the protein component of the complex enhances the catalytic activity, but without it the complex can still work.
