Answer:
B). Dependent Premises.
Step-by-step explanation:
A premise is elucidated as the postulation that forms the basis of an entire argument and from which the conclusion is drawn. It functions to support the information.
As per the question, the 'dependent premises' is the type of premise which would be required for the given argument as each information(available literature, majority of writers, Rosenberg's guilt, etc.) is logically associated to one another and functions to back the conclusion 'they may well have been innocent'. Therefore, option B is the correct answer.
