Bacteria that can grow in the presence or absence of oxygen (o2) are called hints bacteria that can grow in the presence or absence of oxygen (o2) are called microaerophiles obligate aerobes facultative anaerobes obligate anaerobes

The answer is facultative anaerobes.

The easiest way to obtain the answer is by looking for the etiology and meaning of "facultative", which in biology refers to something that can live under different and opposite circumstances.

The other way of finding the answer is by descartig options.

you are certainly talking about this picture:

a: is the label of the white square, it is showing the  replication fork, formed by helicase (d) ==> so it is the site of dna separation and replication 

b: is a new dna brand that is following directly the replication fork, so it is continuous ==> built continuously from 5' to 3

c: dna polymerase cannot replicate dna on its own, it needs the of their proteins, and one of them plays the role of a clamp which fixes  the dna with the dna template and increases  the processivity of the enzyme. ==>   stops polymerase from falling off the  template.

d: is the enzyme responsible for forming the replication fork (helicase) ==> unwinds and separates dna into two strands

e: is the delayed strand, it is built  in the opposite sense of the helicase, so dna will be built in fragments ==> built  fragments from 5' to 3 joins

and finally f: is the enzyme that builds  the new dna strand (dna polymerase) ==>   adds nucleotides to make a new dna helix.
