Which choice completes the text so that it conforms to the conventions of Standard English? While many video game creators strive to make their graphics ever more ______blank others look to the past, developing titles with visuals inspired by the '8-bit' games of the 1980s and 1990s. (The term '8-bit' refers to a console whose processor could only handle eight bits of data at once.)

Choice C is the best answer. The convention being tested is punctuation between a subordinate clause and a main clause. This choice correctly uses a comma to mark the boundary between the subordinate clause ('While…lifelike') and the main clause ('others look to the past'). Choice A is incorrect because it results in an incomplete sentence with no main clause. Choice B is incorrect because it fails to mark the boundary between the subordinate clause ('While…lifelike') and the main clause ('others…past'). Choice D is incorrect because it results in an incomplete sentence with no main clause.
