Tapeworms differ from other flatworms in that for movement: O a. They have well-developed muscles for active movement. O b. They can attach by hooks and a ring of suckers, but otherwise have little activity. O c. They permanently glue themselves in a fixed position. O d. They have a pair of suckers that can attach and release. They move slowly by passing waves of muscular contraction along their body. e.
