OG详解-OG2 文法 Q9

Choice C is the best answer. The convention being tested is punctuation between a subject and a verb. When, as in this case, a subject (“her 2019 novel Gingerbread”) is immediately followed by a verb (“offers”), no punctuation is needed. 
Choice A is incorrect because no punctuation is needed between the subject and the verb. Choice B is incorrect because no punctuation is needed between the subject and the verb. Choice D is incorrect because no punctuation is needed between the subject and the verb.
