D Correct answer
Explanation

From the premises, we know all pens are elephants, and some elephants are cats. However, the cats that are elephants might be entirely separate from the pens; we cannot determine if any pens are cats, if no pens are cats, or if all pens are cats. Without additional information about how the some elephants relates to pens, none of the specific conclusions (A, B, or C) can be logically derived.
