which choice completes the text so that it conforms to the conventions of standard english?
a the silk road that through
b the silk road that, through
c the silk road, that through
d the silk road, that through,

Explanation:

To solve this, we analyze each option for grammatical correctness. The sentence structure requires a relative clause. Option B: "the Silk Road that, through" is correct. The "that" introduces the relative clause, and the comma after "that" properly separates the clause from the main sentence structure when considering the flow of the sentence. Option A is incorrect as "that through" is ungrammatical. Option C and D have incorrect comma placements and ungrammatical structures.

Answer:

B. the Silk Road that, through
