    You have posted two problems. Who wrote these problems?
    I ask that because both use non-standard definitions.
    Does “anti-reflexive” mean "irreflexive?” If not then the proposition is false.
    Your other question is meaningless unless B \subseteq A

    I suspect that someone with a minimal knowledge of the area of mathematics wrote these.
    Please review the question and correct any miss-typing.
