Answer:

B) It keeps the heat inside of the building.

Explanation:

An insulator during winter is needed to stop the heat flow from going outside.

A Fiberglass insulation is made of plastic and tiny pieces of glass. Glass is a non conductive heat material that will stop the scape of heat from a building during winter. In winter if one place is warmer than other, for example the inside of a building and the outside respectively, heat will tend to flow from the warmest place to the coolest place in order to valance the difference in temperature and reach a thermal equilibrium, to prevent this we use insulators.
