Answer:
Policy persuasive speech.
Explanation:
It should be understood that policy persuasive speech is one of the types of persuasive speech and it is commonly used when there is a policy that is guiding the implementation of a thing. For example, the United States Pharmacopeia was adopted in 1906 and is issued every 5 years under the supervision of a national committee of pharmacists, scientists, and health care providers to provide information concerning drug purity and strength. This means that there is a body or policy guiding the pharmacist and a policy persuasive speech should be guided by that.
