Identify and describe the four classical orders and their architectural characteristics.

• A. Doric: sturdy, plain capital, no base; Ionic: scroll capital, base; Corinthian: ornate acanthus leaves; Tuscan: simple, unfluted shaft with plain capital and base.
• B. Doric: ornate capital; Ionic: base; Corinthian: plain; Tuscan: fluted shaft.
• C. Doric: slender column; Ionic: fluting; Corinthian: plain capital; Tuscan: heavy base.
• D. Doric: scroll capital; Ionic: plain shaft; Corinthian: unfluted; Tuscan: ornate capital.

Answer: (A)

The essential idea here is how the four classical orders are defined by their defining features—capital shape, whether they have a base, and how the shaft is treated. Doric is the stout, plain style with a simple capital and no base, usually paired with a sturdy, fluted shaft. Ionic is lighter and more decorative, featuring a scroll-like capital and a base under the shaft, which helps with its column height and visual lightness. Corinthian stands out as the most ornate, with a capital adorned with acanthus leaves (and typically a base) atop a fluted shaft. Tuscan is the simplest of the group, with a plain capital and base and an unfluted shaft.

The description in the option aligns with these distinctions: Doric described as sturdy with a plain capital and no base; Ionic with a scroll-capital and base; Corinthian as ornate with acanthus leaves; Tuscan as simple with an unfluted shaft and plain capital and base. That combination captures the core differences among the orders. Other descriptions conflate or misstate these traits (for example, attributing ornate capitals to Doric or fluting to Tuscan), which is why this set best matches the established characteristics.
