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

The correct option is B only transitive

A number can't be less than itself.So,this less than relation is not reflexive.
If $a<b$ ,then $b$ can't be less than $a$.So,this is not symmetric.
If $a<b,b<c$ then $a<c$ .So,this relation is transitive.
