The discovery of ribozymes supported a hypothesis, known as the RNA World Hypothesis, that earlier forms of life may have relied solely on RNA to store genetic information and to catalyze chemical reactions
The presence of ribosomes that assemble proteins are also a kind of ribozymes and thus this all supported the RNA world hypothesis.
So, the correct option is 'Ribozymes are RNA molecules that have been shown to catalyze reactions'
