c and d
Explanation:
<u>A species of an organism with cell wall that lacks peptidoglycan is definitely not a bacterium because bacterial cell walls usually have peptidoglycan.</u>
One particular group of organisms whose cells have cell walls but lack peptidoglycan is Archaea.
<em>Archaea represents a group of prokaryotes that are able to survive in extreme conditions such as high temperature, pressure and salinity. As such, they could inhabit hydrothermal springs as well as alkaline hot springs.</em>
Hence, thermoacidophile <em>Sulfolobus acidocaldarius </em>is likely to be an Archaea and could inhabit both hydrothermal springs and alkaline hot springs.
The correct option is option c and d.
