An RNA molecule that acts as an enzyme is called a

Explanation:
RNA can act as enzymes because it can fold into precise shapes that position functional groups to speed up chemical reactions. When an RNA molecule has catalytic activity, it’s called a ribozyme. This shows that catalysts aren’t limited to proteins. Examples include RNA molecules that catalyze splicing or cleavage reactions. The other options refer to non-RNA enzymes: a protease is a protein enzyme; a DNAzyme is a DNA-based catalyst; and while the ribosome has RNA-driven catalytic activity, the standard term for an RNA-based catalyst is ribozyme.
