Answer: a. Dendritic
Explanation:
A dendritic drainage pattern is the most common form and looks like the roots of trees branching pattern. It is a drainage pattern in which streams branch in many directions randomly at different angles as well. It develops in regions that have underlying homogeneous material. This means the subsurface geology has a similar resistance to weathering resulting in no seeming control over the direction the tributaries take. It is produce in streams that receive several tributaries that are fed by smaller ones. Tributaries link up a larger stream at acute angle ( angle less than 90 degrees). It can be indicated when streams flow across horizontally and complex crystalline rock/homogeneous strata help in resisting erosion uniformly.
The process that is responsible for the formation of a normal fault is
when horizontal stresses occurs in brittle rocks and the hanging wall blocks moves down relative to the footwall blocks

Explanation:
Catastrophism is the theory that the Earth has largely been shaped by sudden, short-lived, violent events, possibly worldwide in scope, this contrast with Uniformitarianism that suggests that the landscape developed over long periods of time through a variety of slow geologic and geomorphic processes.
To meaningfully study the past, we must assume the same or similar mechanisms operated then as now, following this idea we conclude that uniformitarianism is a more logical theory, <em>geologists then consider periodic catastrophe (volcanic eruptions, earthquakes, meteorite impacts, and storm deposits) is one of those processes uniformitarianism suggests.</em>
