3. An award presentation
4. A keynote address

A) a toast

Step-by-step explanation

It is imperative to note that a toast specifies a form of communication that involves a brief conversation of congratulations, gratitude, and commemoration of a person. Since it constitutes a special occasion (i.e. wedding, a celebration or prosperous business project), the type of speech that is favorable is a toast. As such, a toast must be kept brief and to the point to attract and maintain the attention of all the invited guest. The person who makes the toast must also be kind in the sense that he/she should be generous and courteous to the audience.
