Why Not Option C in Que 2 of Set A ?
@anup Patel

Actually it is not reflexive
as 0D0 is undefined.
Qus no. 15, answer should be C
it is in BCNF too :(

Abbas2131 then which option is correct
Not Reflexive
Antisymmetric
Transitive

Yes, The relation is : not reflexive, Antisymmetric, Transitive.

 

I don't understand how they have given Not antisymmetric, because the definition states that If aRb and bRa then a=b, which i guess should be true for this relation
