Solution

True chordate features: closed circulatory system (B correct) and paired pharyngeal gill slits at some life stage (C correct). The nerve cord is dorsal, hollow and single (A wrong). The heart is ventral, not dorsal (D wrong). Chordates are triploblastic and coelomate, not pseudocoelomate (E wrong).
