B is the answer to this question. The most appropriate to use is the word “sends.” Mr. Hawkins is only one person, which means that the verb that will follow someone, a collective noun, should come with an ‘s’ to show the singular form.
It will not be ideal for writing someone send as it will not be appropriate to the rules of the English language. Sent is also not suitable because Mr. Hawkins is still requesting. This means that the action has not been done yet. To send will not be appropriate too because there is no need to add an article before the verb to complete the sentence.
