Answer:
The correct answer is option D, chemical sedimentary rock
Explanation:
Both stalactites and stalagmites are called drip stone as they are formed of the dripping water consisting of minerals. Both stalactites and stalagmites hang up from the ceiling of caves. These are also refereed to as Chemical sedimentary rocks formed by precipitation. The three major processes involved in the formation of these two rocks are –
a) Physical weathering – which disintegrates the minerals contained in the igneous, sedimentary, or metamorphic rock
b) Chemical weathering – which involves dissolution of weathered rock minerals
c) Precipitation of the dissolved minerals.
