b. all soft corals have zooxanthellae interdependence.
c. all soft corals reproduce only asexually.
d. all soft corals secrete calcium carbonate to create an exoskeleton.
e. all soft corals contain sclerites for support.

Explanation:

Soft corals have sclerites (small calcareous structures) for support. Not all soft corals help build reefs (A is wrong). Not all have zooxanthellae (B is wrong). They can reproduce sexually and asexually (C is wrong). They don't secrete calcium carbonate for exoskeletons like hard corals (D is wrong).

Answer:

E. All soft corals contain sclerites for support.
