Question

The relation "less than" in the set of natural numbers is :

• A. only symmetric
• B. only transitive
• C. only reflexive
• D. equivalence relation

Answer 1

Answer: (B)

Only transitive
Since for three numbers a, b, c a is less than b and b is less than c
$\Rightarrow$ a is less than c.
not reflexive and symmetric
Since a is not less than a and a is less than b does not implies b is less than a.
