Which choice completes the text so that it conforms to the conventions of Standard English?

A

dash: had

B

dash; had

C

dash. Had

D

dash, had

Correct Answer: D

Choice D is the best answer. The comma correctly connects the inverted conditional dependent clause ("had she not stumbled") to the main clause.

Choice A is incorrect because a colon is inappropriate to connect a conditional clause here. Choice B is incorrect because a semicolon separates two independent clauses. Choice C is incorrect because the second part is a dependent clause fragment.
