    The answer to your question is:

    Explanation:

    Covalent bonding is the process of sharing a pair of electrons between to atoms so they become stable.

    A. In fact a process of split a pair of electrons do not happen in nature, there is no bonding that behaves in this way.

    B. This is a definition of covalent bonding, in this bond, the elements share a pair of electrons to complete 8 electrons in their outermost shell.

    C. The bond described here is Ionic bonding in which one element loses electrons and the other gains them.

    D. The process describe here is not about any kind of bonding.

    E. This do not happen in a covalent bonding, it could be the description of metallic bonding.
