(B) Given the set $A = \{1, 2, \{3, 4\}, 5\}$.$1$. The elements of set $A$ are $1$,$2$,${3, 4}$,and $5$.$2$. Since ${3, 4}$ is listed as an element within the set $A$,the statement ${3, 4} \in A$ is true.$3$. The statement ${3, 4} \subset A$ is false because the elements of the set ${3, 4}$ are $3$ and $4$,which are not elements of $A$.$4$. The statement $1 \subset A$ is false because $1$ is an element of $A$,not a subset ($1 \in A$ is true).$5$. The statement ${1, 2, 5} \in A$ is false because the set ${1, 2, 5}$ is not an element of $A$ (though it is a subset of $A$).

Let $A = \{1, 2, \{3, 4\}, 5\}$. Which of the following statements is true?
