Communication is a very vital part of a research by a scientist like you. The typical methods of classroom scientific communication include lectures, lab reports, term papers and poster presentations. Writing papers can help you enhance your your science productivity and at the same time retaining some body of knowledge that would be of help to future researches. The presentations you make widens your connection and awareness to the community. Moreover, the discussions you make can facilitate learning and exchange of ideas.

The correct answer is - C. -1.9 C degrees.
The sea ice in the polar oceans needs little lower temperatures to start forming than what it would need if it was't forming on a saline water. The freshwater starts freezing as the temperature goes bellow 0 C degrees, but that is not the case with the saline water. The saline water, because of the salt that prevents the freezing to a certain point, needs temperature of -1.9 C degrees to start freezing. Once this temperature is reached, the salt can not prevent the freezing anymore, so the water on the polar oceans starts to freeze.
