If a relation $R$ on the set $\{1, 2, 3\}$ be defined by $R = \{(1, 2)\}$, then $R$ is

transitive

The correct answer is Option (2) → transitive ##

$R$ is not reflexive.

Because $(1, 1), (2, 2), (3, 3) \notin R$

$R$ is not symmetric.

Because $(1, 2) \in R$ but $(2, 1) \notin R$

$R$ is transitive.

Because single element relation is always transitive.
