Selective Optimization With Selection.

Explanation:

It is known that this theory was widely known from 1980s and was postulated by a man called Baltes. Baltes here argued that as individuals advance through life they are increasingly faced by age related deficits which place limits on their cognitive and behavioral resources. Tackling these limits placed on domains, individuals will begin to invest resources into particular styles and behaviors that are deemed adaptive to the new constraints.

D) Psychrotrophs.

Explanation:

Psychrotrophs are those bacteria which can tolerate cold temperature and have optimum growth above 15 degree Celsius.
Halophiles prefer high salt concentration.
Mesophiles prefer temperatures with a average of 37 degree Celsius.
Anaerobes grow in absence of oxygen.
In the given experiment, none of the bacterial cultures were placed in saline or anaerobic conditions. So, the bacterial species is not an anaerobe or halophile.
Again the cultures did not show growth at 37 degree celsius so they are not mesophiles.
Maximum growth at 22 degree celsius and a little growth in refrigerator make it obvious that the species is a Psychrotroph.
