Which of the following phyla contains members that are notorious for causing serious diseases in humans?

• A. Cnidarians
• B. Segmented worms
• C. Flatworms
• D. Chordates

Answer 1

The correct option is C Flatworms

Flatworms are generally parasitic in nature and feed on the host organism's nutrition often causing disorders as a consequence. When it comes to parasitic infection, flatworms and roundworms are likely culprits. These two types of parasitic worms can be found in a variety of habitats. They aren't always visible to the naked eye. Tapeworms and flukes cause diseases in humans and their livestock, whilst monogeneans can cause serious losses of stocks in fish farms. Schistosomiasis, also known assnail fever, is the second most devastating parasitic disease in tropical countries, behind malaria.

So, the correct option is, 'Flatworms'.
