Answer:
A. Platyhelminthes
Read Explanation:
Bilaterally symmetrical and acoelomate animals are found in the phylum Platyhelminthes.
Explanation:
Platyhelminthes (flatworms) are characterized by being bilaterally symmetrical (their body can be divided into two mirror-image halves) and acoelomate (lacking a true body cavity or coelom).
Aschelminthes (roundworms) are bilaterally symmetrical, but they are pseudocoelomate, meaning they have a false body cavity.
Annelida (segmented worms) are bilaterally symmetrical and coelomate, possessing a true body cavity.
Ctenophora (comb jellies) are radially symmetrical and acoelomate.
