Answer:
<u><em>C. bacteria genetically modified to be antibiotic-resistant</em></u>
Explanation:
<em>Genetically modifying organisms can be either beneficial or harmful for humans. As we can be infected by bacteria, we developed antibiotics to fight those infections, and this saves many lives as it is an efficient medicine.</em><em> But when a bacteria is genetically modified to be resistant to antibiotics, we can be harmed as we don't have a way to fight the infection and the bacteria will spread (even maybe kill us).</em><em> T</em><em>herefore, bacteria that are antibiotic-resistant do not benefit humans, and the correct answer is C. bacteria is genetically modified to be antibiotic resistant.</em>
