Right answer is (c) Over and Intensive Irrigation

For explanation I would say: When intensive irrigation is practiced, it only irrigates a small portion of the whole irrigable land. Due to this over irrigation it leads to heavy percolation which leads to rising of water table causing waterlogging. So, to prevent waterlogging extensive method of irrigation is recommended.
