• A)that some bacteria can survive at higher temperatures compared to archaeons
• B)that some bacteria can survive at high temperatures, although archaeons can survive in much hotter environments
• C)that archaeons prefer colder environments compared to bacteria
• D)that bacteria and archaeons can likely both survive at temperatures of 122°C
