Explanation:

To determine the correct answer, we analyze the punctuation and structure. The phrase "large wooden or metal surfaces" is a parenthetical explanation of "panels", so em dashes (—) should be used to set off this explanatory phrase. Option A uses em dashes correctly to enclose the explanation. Option B uses a comma which is incorrect for this parenthetical. Option C incorrectly places a dash between "wooden" and "or", disrupting the phrase. Option D lacks the appropriate punctuation to set off the explanation.
