The answer to the question is **c) parent**.

### Explanation:
In the context of a binary tree, every node can have up to two children. The relationship among these nodes includes terms such as "parent," "child," "sibling," and "leaf."

1. **Parent**: This is the node directly above another node. For example, if node A has nodes B and C as its children, then A is the parent of B and C.
2. **Child**: Nodes that are directly below a node are referred to as its children.
3. **Sibling**: Nodes that share the same parent are called siblings.
4. **Leaf**: A leaf node is a node that does not have any children.

Thus, in this specific question, since the node directly above another is what defines a parent, the correct choice is **c) parent**.
