Answer 1

The correct option is D

1, 2 and 3
Explanation:
Depending on the underlying rock structure, slope of land, and climatic condition of the particular area the streams within a drainage basin form certain patterns and these are dendritic, trellis, rectangular and radial patterns. In the same drainage basin combination of several patterns may be found. Climate is an important factor as it basically can feed the river at its source. If the source region goes dry then the river or drainage patterns would not be formed.
