Which of the following statements is wrong?

Statement 2 is incorrect because the oceanic crust (sea-floor) is significantly younger than the continental crust (land). Scientific evidence shows that oceanic crust is continuously recycled into the mantle through subduction, meaning it is nowhere older than approximately 200 million years [1][t1]. In contrast, continental rocks are more stable and can be as old as 3,200 to 4,000 million years [1][t2]. Statement 1 is correct as stalactites and stalagmites are calcium carbonate (lime) deposits formed by mineral precipitation in caves [t5][t7]. Statement 3 is correct because the Earth's first rocks were igneous, formed from the cooling and solidification of molten magma [c4][t3]. Statement 4 is correct as sedimentary rocks are frequently termed 'aqueous' rocks when formed through the agency of water, which transports and deposits the constituent sediments [t3].
