Which of the following is an empty set?

a $\{0\}$
b $\{x \in \mathbb{N} : 10 < x < 11\}$
c $\{1\}$
d $\{x : x$ is even $\}$

ব্যাখ্যা

There is no natural number strictly between $10$ and $11$ , so the set $\{x \in \mathbb{N} : 10 < x < 11\}$ has no elements and is therefore empty. The other options each contain at least one element.
