Choice B is the best answer. The convention being tested is punctuation between a supplementary element and a main
clause. This choice correctly uses a comma to mark the boundary between the supplementary phrase (“While...1947”), which
indicates when the action occurred, and the main clause (“Howe had a handheld camera operator wear roller skates”).
Choice A is incorrect because a comma paired with the conjunction “and” can’t be used in this way to mark the boundary
between the supplementary element (“While…1947”) and the main clause (“Howe…skates”). Choice C is incorrect because
the conjunction “and” can’t be used in this way to join the supplementary element (“While…1947”) and the main clause
(“Howe…skates”). Choice D is incorrect because it fails to mark the boundary between the supplementary element and the
main clause with appropriate punctuation.
