Answer:
d. plasmids, nucleiod, and endospore
Step-by-step explanation:
Bacteria are prokaryotic organisms i.e. they do not possess a well defined nucleus in their cells. However, according to this question, some bacteria are said to possess antibiotic resistance, as well as the ability to survive through adverse conditions. These two characteristics of some bacteria is attributed to the possession of a plasmid and endospore respectively.
A plasmid is a circular extra-chromosomal DNA found in bacterial. It is termed "extra" because it is different from the DNA of the bacteria and carries different genes. The genes contained in the plasmid often gives the bacteria added advantage like antibiotic resistance. On the other hand, endospores are asexual spores produced by bacteria in order to withstand adverse environmental conditions like drought etc.
