Explanation:

Biocontainment involves measures to prevent the spread of biological agents. In the context of the text, it's about isolating potentially infectious elements (like a person bitten by a monkey who goes into a biocontainment bubble). The first option about confining live animals is too broad as it doesn't specifically target biological containment for infectious purposes. The second option about preserving deadly diseases is not the main idea - biocontainment is more about isolation to prevent spread rather than just preservation. The fourth option about describing a region is off - topic. The third option, the isolation of contagious organisms, aligns with the concept of biocontainment as shown in the text (using the bubble to isolate someone potentially exposed to a contagious situation).

Answer:

the isolation of contagious organisms
