Answer:
a. Form and premises.
Form is about the relationship between what is written and what is spoken. Premises are hidden assumptions.
Step-by-step explanation:
The term "argument" is defined in logic as a group of sentences or statements that consists of one or more than one premises and it has only one conclusion.
And "premises" are considered as assumptions that something mentioned in the statement is true or false.
"Form" is the another name of the statement that is given and spoken in the question.
Thus the answer is
a. Form and premises.
Form is about the relationship between what is written and what is spoken. Premises are hidden assumptions.
