Rosario (Spanish pronunciation: [roˈsarjo]) is the largest city in the province of Santa Fe, in central Argentina. It is located 300 km (186 mi) northwest of Buenos Aires, on the western shore of the Paraná River.
In which plate boundary two plates move towards each other and collide called convergent plate boundary. And causes devastation. E.g. Earthquake, Vulcanicity. In which plate boundary two plates move in opposite direction and do not collide called divergent plate boundary. Mountain building is the result of this type of plate boundary's action. In transform fault both the plates slide each other and causes fault in the sea floor.
Explanation:
Plate is a rigid and solid crustal block which is mobile in character and found in the asthenosphere in the upper mantle. It prevails in semi liquid and viscous condition where plates move easily. There are seven major plates and twenty minor plates. Plates are of two types. Continental plate and oceanic plate.
Where two plates collide with each other that area is known as plate boundary and the edge of plate is known as plate margin. Plate boundary is of three types: Convergent, divergent and transform plate boundary. These are also known as constructive, destructive and neutral plate boundaries.
The subject of science is very broad. With that being said, I think there is no official regulatory board that decides the branches of science. Scientific developments are products of joined efforts of different scientists. These scientists could rebuke another's work provided there is evidence. As long as the theory is generally accepted by the scientists and no one rebukes it effectively, then it is a generally accepted fact and everyone adapts it.
Hence, the answer is B.
