Solution

The correct option is E Both C and D
Protochordates are the animals having a dorsal hollow nerve cord, pharyngeal gill slits, and a notochord. They are usually referred to as the oldest chordates. They mainly include tunicates and cephalochordates. They are bilaterally symmetrical and possess a coelom. They do not have a closed circulatory system or jointed legs.
So, the correct answer is 'Both C and D'.
