Note: Helium is not explosive. It is an inert gas. Hydrogen is explosive.
Answer number 2 is correct and gives a great example of what would happen and why.
Helium is lighter than air. If a balloon has helium in it, it will float because of this. If the balloon has air mixed with the helium, the mixture will still be lighter than air without the helium, so will still float, but the more air in the mixture, the lower the balloon will float.

Your ballon would contain helium and oxygen gases. The two gases would not react with each other, given that helium is a "noble gas" or an inert gas. Probably the oxygen would react with itself, producing oxygen gas.
The balloon would float, since you can find both helium and oxygen in the air. I suspect that it would probably not float as high as if it contained pure helium. As always happens with balloons that contain helium, the gases (in this case oxygen and helium) would leak out slowly.

It wouldn't float as much.
Just imagine a helium balloon left for a couple of days. As oxygen seeps through the rubber and helium seeps out, the balloon loses loft.

Wouldn't that be explosive?
