Question

The relation $R$ defined in $N$ as $a blank R blank b ⟺ b$ is divisible by $a$ is

Reflexive but not symmetric
Symmetric but not transitive
Symmetric and transitive
None of these

The correct answer is: Reflexive but not symmetric

For any $a element of N comma$ we have $a vertical line a$
Therefore $R$ is reflexive
$R$ is not symmetric, because $a blank R blank b$ does not imply that $b blank R blank a$
