Question

A relation between two persons is defined as follows:
$a R b left right double arrow a$ and $b$ born in different months. Then, $R$ is

Reflexive
Symmetric
Transitive
Equivalence

The correct answer is: Symmetric

Let $open parentheses a comma b close parentheses element of R.$ Then,
$a$ and $b$ are born in different months $rightwards double arrow left parenthesis b comma a right parenthesis element of R$
So, $R$ is symmetric
Clearly, $R$ is neither reflexive nor transitive
