On $A = \{1, 3, 5\}$, the relation $R = \{(1, 1), (3, 3), (5, 5), (1, 3), (3, 5)\}$. Which of these describes $R$?

Explanation

1. 01

   It is reflexive, since every $(a, a)$ is in $R$.

2. 02

   It is not symmetric, since $(1, 3)$ is in $R$ but $(3, 1)$ is not, and not transitive, since $(1, 3)$ and $(3, 5)$ are in $R$ but $(1, 5)$ is not.
