Which of the following is/are true ?
- A. $\text{R}$ is a reflexive relation on a set $\text{A}$, then $\text{R}^{n}$ is reflexive for all $n\geq0$
- B. Relation $\text{R}$ on set $A$ is reflexive if and only if inverse relation $R^{-1}$ is reflexive.
- C Relation $\text{R}$ on set $A$ is antisymmetric if and only $R \cap R^{-1}$ is a subest of diagonal relation $\Delta = \left \{ (a,a) \; | a \in A \right \}$
- D. $M_{S\circ R} = M_R \; \odot M_S$ where $\odot$ is boolean product.
