Answer:
The correct answer is "similar evidence collected in multiple experiments by different people ".
Step-by-step explanation:
Modern theories proposed in scientific researchers are based on similar evidence collected in multiple experiments by different people. Nowadays, specialized journals serve as a platform for scientific divulgation through the scientific community around the world. When similar evidence is obtained from multiple experiments performed by different people, the scientific community propose a theory to explain the nature of the evidence. This is the case for modern cell theory.
