Answer:
B- Columns is correct.
Step-by-step explanation:
Architecture. The great architecture of the Greeks has not been surpassed in modern times. The Parthenon, designed by the architects Ictinus and Callicrates, was built between 448- 437 B.C., under the supervision of Phidias, a great sculptor. It still stands in Athens, a classic example of Grecian models. The Greeks introduced to the world three kinds of columns. All three kinds of columns have been used in the construction of important structures from that time until the present.
