Answer: Third option is correct.
Step-by-step explanation:
Since we have given that
[tex]\{x|x\epsilon N, x < 3\}[/tex]
That means the set must have numbers less than 3.
But the set belongs to natural number.
So, it contain only positive integer starting from 1.
So, Set must have
[tex]\{1,2\}[/tex]
Hence, Third option is correct.
