When water reacts with sodium in rocks, particularly in the context of weathering processes, the products typically include clay minerals and a saline solution (which can include sodium compounds, often in the form of salts).
Given the options you've provided, "salt solution and clay minerals" would be the most accurate response. This reflects the process of weathering where sodium ions can be leached out and clay minerals are often formed as a result of the alteration of feldspars and other minerals present in the rock.
