What type of Magnetic material is plastic?
a. diamagnetic d. paramagnetic
b. ferromagnetic e. nonmagnetic
c. magnetic
Plastic: why not non magnetic?
Take a look at this:

In addition, while water and oxygen can be magnetic, I don't see a reason why plastic can't!

IT could be diamagnetic according to electron configuration from Chemistry. But without specific formula I would say your best bet is e nomagnetic.

OK, most plastic is non-magnetic. The reason is that it is mostly made of carbon. Carbon does very symmetrical, non-polar bonds. Magnets traditionally (notice that word, traditionally) are made of metal. Iron or nickel or cobalt.
Water is non-magnetic. I am not sure where you got that. Oxygen also is non-magnetic. Granted, water has hydrogen bonding which is a charge - charge attraction, but not magnetic.
Notice on your link that plastic was the very first plastic magnet. Neat stuff. Sometimes you find you know more than your science books. Books are often 5 years or more out of date.

The answer is B. That is because the plastic is alloyed with ferrous iron, thus making it magnetic.
