Solution

The correct option is C They can absorb oxygen through body wall.
The roundworms belong to the group of Aschelminthes. These worms do not have a developed respiratory which can allow the oxygen to enter and circulatory system which can help in the distribution of the oxygen to the different cells. The body wall is thin and allows the oxygen to get diffused in the cells and this allows the organisms to perform the metabolic reactions.
Thus, the correct answer is option C.
