The correct answer indicates that the black marks on the given map represent the distribution of mica.

Let`s understand each option:

Option 1: Asbestos - Asbestos deposits usually occur in extensive layers. The black marks on the map do not represent this particular mineral`s typical spread, making option 1 incorrect.

Option 2: Gypsum - Gypsum is often found in large quantities in sedimentary rocks on every continent. The map probably doesn`t show the distribution of this mineral, discarding option 2.

Option 3: Limestone - Limestone is mostly found beneath the ocean floor or in shallow areas. It`s typically not spread sporadically, which rules out option 3.

Option 4: Mica - Mica is primarily located in specific regions with volatile geological activity. The distribution of black marks on the map matches the typical dispersal pattern of mica deposits, making this the correct answer.
