(N/A) Given the set $A = \{1, 2, \{3, 4\}, 5\}$.
The statement ${1, 2, 5} \subset A$ is correct.
Reason: $A$ set $X$ is a subset of $A$ if every element of $X$ is also an element of $A$. Here,the elements of ${1, 2, 5}$ are $1, 2,$ and $5$. Since $1 \in A, 2 \in A,$ and $5 \in A$,the statement ${1, 2, 5} \subset A$ is true.
