A binary relation $\mathrm{R}$ over a set $\mathrm{A}$ is called a "GO Relation" if for all $\mathrm{x}, \mathrm{y}, \mathrm{z}$ $\in A$, if $x R y$ and $x R z$, then $y R z$.
Which of the following is/are true about a relation $\mathrm{R}?$
- If $R$ is a reflexive and GO relation then $R$ is symmetric.
- If $R$ is a reflexive and GO relation then $R$ is transitive.
- If $R$ is a GO relation then $R$ is reflexive.
- If $R$ is an equivalence relation then $R$ is a GO relation.
