The correct answer is none of the above.
Bacterial cells can transfer genetic material through a process called bacterial conjugation. This process involves the direct physical contact of the bacterial cells and a horizontal gene transfer. The genes which are transferred are most of the times beneficial for the recipient, such as genes for antibiotic resistance.
In this example, bacterial cells cannot have physical contact, since they are separated by a glass filter. Therefore, the bacterial conjugation cannot happen. Given that no gene transfer can be achieved, the AY strain remains bio- trp- and is unable to grow on any medium that lacks bio or/and trp.
Runoff in neighborhoods can be a problem because as the water runs it can collect pollutants such as oil, pesticides, bacteria, etc. These pollutants can end up in our drinking water or can run into our fishing supply and even our swimming water... I wouldn't want to be swimming or eating fish that was swimming in pesticides and bacteria.
