    I also agree. B and C are correct

    Definitions
    . ==> One instance of any character except the space. For example, .456 matches 1456 or 6456.
    + ==> One or more instances of the immediately preceding term. For example, tre+ matches messages with tree or tread but not trough.
    * ==> Zero or more instances of the immediately preceding term. For example, 234* matches 2345698 or 2347985

    .*14203+ (21870 | 10458)

    (.) Can begin with one instance of any character except space. Meaning it can begin with anything.
    The Any Characters we chose in (*) is preceeding (*)

    What determines the answer are these
    Must have one or more instances of 14203 (Makes answer A wrong)
    Then can have either 21870 or 10458 at the end (Makes answer D wrong)
