D. by sharing it's 1 electron with another element a single covalent bond is formed which shows the Hydrogen as sharing two electrons, giving it a Helium (the first Noble gas) electron configuration.

A. Flourine is really electronegative, but not enough to rip the electrons away from the other atom, so it would form a polar covalent bond.

"B"
"The noble gases are the chemical elements in group 18 (old-style Group 0) of the periodic table. This chemical series contains helium, neon, argon, krypton, xenon and radon."
