K Determine whether $\subseteq$, C, both, or neither can be placed in the blank to make the statement true. \[ \{1,4,7,10,13\} \_\{7,1,4,10,13\} \] Choose the correct answer below. only $C$ only $\subseteq$ both $\subseteq \& \subset$ None of the above

Step 1 ：The question is asking to determine the correct relation between two sets. The first set is {1,4,7,10,13} and the second set is {7,1,4,10,13}. The order of elements in a set does not matter, so these two sets are actually the same.

Step 2 ：Therefore, the correct relation is \(C\) (equals), and also \(\subseteq\) (is a subset of), because every set is a subset of itself.

Step 3 ：Final Answer: \(\boxed{\text{both } \subseteq \text{ and } C}\)
