Answer:
OB. Request for action.
Step-by-step explanation:
In the given message from the head of the HR department of a business, we see the writer talk of the hiring requirements for the company's new research division manager. The business letter contains the requirements or certain qualities from the applicant and then ends with a request for a meeting.
This pattern of the letter shows a request for action from the recipient of the HR letter. This is understood by the closing line "Please respond tomorrow by 11 am", which means that the reply is expected by 11 am the next day.
Thus, the correct answer is option B.
