The number of correct statements amongst the given is:
| Statement I: | Parasitism has evolved in many taxonomic groups from plants to higher vertebrates. |
| Statement II: | Many parasites have evolved to be host-specific and both tend to co-evolve. |
| Statement III: | All parasites have only one primary and one intermediate host. |
| Statement IV: | Only a few of the parasites harm their hosts. |

The given picture shows Cascuta, commonly found growing on hedge plants. Such relationship is also exemplified by:
| I: | Lice on humans and ticks on dogs |
| II: | Marine fish infested with ectoparasitic copepods |
| III: | Female Anopheles biting human beings |
| IV: | Tapeworm in the human alimentary canal |

Consider the two statements given below:
1. Only Statement I is correct
2. Only Statement II is correct
3. Both Statement I and Statement II are correct
4. Neither Statement I nor Statement II is correct
| Statement I: | The morphological and anatomical features of endoparasites are greatly simplified but their reproductive potential is very high. |
| Statement II: | Unlike ectoparasites, endoparasites live inside the host body at different sites and their life cycles are more complex. |
2. Only Statement II is correct
3. Both Statement I and Statement II are correct
4. Neither Statement I nor Statement II is correct
