I'm going to guess that it's the second option, "New matter only enters the biosphere in the form of precipitation" because it bothers me that the writer said "new matter" and everything else seemed right to me.
The last two are definitely true. I'm a bit iffy about the first option because I know that autotrophs take the energy from the sun, then primary consumers eat them and then everything eats one another afterwards. So everything moves from the bottom of the food pyramid up. There are decomposers which take dead matter from any trophic level and bring it up, which, I guess, is still in the same direction on the food pyramid.
New matter can probably enter the biosphere in other ways like a meteor hitting the earth or something. The water from precipitation never left the biosphere, so that's where it's wrong.
I hope this helps.
