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

A

pledge

B

vows

C

promise

D

Correct Answer: D

Choice D is the best answer. The phrase "one of his" must be followed by a plural noun ("assurances").

Choice A is incorrect because "pledge" is singular. Choice B is incorrect because "vows" is plural but syntactically less common in this context. Choice C is incorrect because "promise" is singular.
