Quizplus · Accepted Answer

Limestone is a sedimentary rock that is primarily composed of calcium carbonate. This makes it highly soluble in water and weak acids, such as carbonic acid. Quartzite and quartz-rich sandstone, on the other hand, are primarily composed of silica, which is relatively insoluble in water and acids. Therefore, C is the best answer as it is the only option that is easily dissolved by water and weak acids.
