Explanation:

Limestone (Marble) is composed mainly of calcium carbonate ($CaCO_3$). Acid precipitation contains acids like sulfuric acid ($H_2SO_4$) and nitric acid ($HNO_3$). These acids react with calcium carbonate in a chemical reaction. For example, $CaCO_3 + H_2SO_4=CaSO_4 + H_2O+CO_2\uparrow$. The reaction leads to the dissolution and weathering of limestone (Marble) over time. Granite (Gneiss) has a more complex composition with silicate minerals that are less reactive with common acids in acid precipitation. Sandstone (Quartzite) has a significant amount of quartz ($SiO_2$) which is relatively inert to the acids in acid precipitation under normal environmental conditions.

Answer:

limestone (Marble)
