Which of these is not correct about the tse-tsefly and mosquito? They

The statement "They have intermediate hosts" is not correct for both tsetse flies and mosquitoes. Tsetse flies and mosquitoes both harbour protozoa as disease agents, possess piercing and sucking mouthparts, and inject disease-causing organisms into the bloodstream. However, only some species of mosquitoes have intermediate hosts, which are typically other insects such as snails or mosquito larvae, in the life cycle of the parasites they transmit. Tsetse flies, on the other hand, do not have intermediate hosts in their transmission of diseases. Instead, they directly transmit the parasites to their mammalian hosts through their bite.
