Right option is (c) In palmate venation, only one strong mid-rib is present
The best explanation: In reticulate venation, veins are arranged haphazardly. However in parallel venation, veins are arranged in a parallel manner. Both the kinds can be further classified into palmate and pinnate. In pinnate venation, only one strong mid-rib is present and in palmate venation more than one strong rib is present. Rice is an example of convergent palmate parallel venation.
