Answer: The correct answer is Impromptu.
Explanation: 
An impromptu speech is a speech that the speaker has to do without being prepared in advance.
<u>In these speeches, the speaker needs to use his/her abilities, knowledge and communication skills to improvise and succeed with the delivery of the speech. </u>
It is proposed by researchers and teachers that practicing impromptu speeches can improve public speaking skills as well as boosting the speakers' confidence.
