A. They live in oceans, are parasites, and reproduce only sexually.
B. They live in fresh water, are parasites, and reproduce only asexually.
C. They live in oceans, are free living, and reproduce sexually and asexually.
D. They live in fresh water, are free living, and reproduce sexually and asexually.

Answer 1

I believe that the answer above is correct, and that D. “They live in fresh water, are free living, and reproduce sexually and asexually” is correct.

Step-by-step explanation:

Some types of planarians live in water, and some live on land. Most planarians live in fresh water and sometimes stay in a big group. Some types are parasites, that means they live off of other living animals.

Answer 2

D. They live in freshwater, are free-living and reproduce sexually and asexually.

Step-by-step explanation:

Most planarians are found in freshwater. Since they reproduce through fission, they reproduce asexually. However, since they are heteromorphic, they also reproduce sexually.
