Let's go through this systematically.
A covalent bond is when two nonmetals share electrons.
Choice "A" describes a metal bonding with a nonmetal. That's an ionic bond. So it's not A.
Choice "B" also describes an ionic bond. So it's not B.
Noble gases don't bond, so it's not "C".
"D" looks right, but first let's check out E.
"E" describes a bond in which both atoms are metals. That's a metallic bond. We don't want that. So it's not E.
Therefore, the answer is D) Atoms are held together by sharing electrons.

D by process of elimination.
A is wrong because that is generally ionic bonding.
B is wrong because that is also ionic bonding.
C is wrong because noble gases will not interact
E is wrong because metallic bonds are a type of covalent bonds.
D is the only possibility.

Covalent bonds happen when atoms share elections so the answer is D.
