Explanation

Total number of species = 15 + 5 + 7 + 23 = 50

Total number of Imperata spp = 23

Percentage occurence of Imperata spp = number of imperata/ total number of species X 100

                                                                = \(\frac{23}{50}\)\(\times 100\)

                                                                = 46% - Option C
