Correct answer: C). Evolution by natural selection, Galapagos finches  

Charles Darwin gave the theory of natural selection in the year 1835 when he visits Galapagos Islands.

There he found several species of finches are adapted to different environmental niches. They have a different shape of the beak, food source they eat and the way they captured the food.

He observes that species vary from island to island, and based on these observations he gave the theory of natural selection.

From the given question the following points lead us to conclude that the colony that will be growing would be of P. aeruginosa :

1. Flat spreading colonies with a metallic sheen on SBA - <em>P. aeruginosa</em> is known to produce smooth colonies with flat edges.

2. Fluorescent green color in the media with clear colonies on cetrimide agar - <em>P. aeruginosa</em> is known to produce pyoverdin which is a fluorescent pigment under low iron conditions.

3. Medium clear colonies that have a "fruity or grape-like odor" on MacConkey Agar - <em>P. aeruginosa</em> has a sweet fruity odor which is its characteristic odor because of the production of trimethylamine.

Thus, from all these characteristics one can conclude that the organism in the culture is <em>P. aeruginosa. </em>
