Answer: The right answer is the D) decorated with a drape of lacy hallmarked silver.
Explanation: Just to elaborate a little on the answer, it can be added that since they are asking for descriptive details that help visualize the specific early Victorian tea set, option A can be discarded, since that set was not representative of Wedgwood's most expensive ceramics. In addition, options B and C should also be discarded, since those are not particularly descriptive details and they do not specifically help visualize the piece. The detail that refers to the specific aspect of the piece—the presence of a drape of lacy hallmarked silver—is, therefore, the one that best helps visualize the artifact.
