    It has to be Dendritic drainage pattern, which is probably found in rocks like granite, gneisses and volcanic rocks also. Dendritic pattern is one of the dominant patterns in the Himala­yas if one observe and also on extensive plateau surfaces like your Deccan plateau. Uniform lithology is prevailed in this pattern. Trellis is mostly associated to folded lithology like anticlines and synclines mainly. And they are also found dominating in areas where the rocks are resistant to weathering. So correct option is (C).
