Answer: A sedimentary process

Moreno · Answer 2

Option (C)

Explanation:

The magma when it comes out to the surface from the greater depth, the magma gets crystallized having the gold in it. These rocks sometimes alter into metamorphic rock due to the extreme pressure-temperature condition. These rocks are affected by the water as it flows over them and over a due course of time, it weathers and erodes the minerals and is carried to some other place. This process of erosion and deposition of minerals is known as the placer deposits.

Thus, Gold is one type of mineral that is distributed by this type of sedimentary process.

Hence, the correct answer is option (C).
