Answer 1

The correct option is B trellised drainage pattern

A rectangular drainage pattern with streams flowing parallel to each other and joining the main stream at right angle is called trellised drainage pattern.

It is a rectangular pattern formed where two sets of structural controls occurs at right angles. In a trellis pattern, the river forms a net like system and the tributaries flow roughly parallel to each other. The old folded mountains of the Singhbhum (Chotanagpur Plateau) have drainage of trellis pattern.
