Answer:
C). Makers of cookware will not find Kitchen a less attractive advertising vehicle because the magazine's name is associated with a competing product.
Step-by-step explanation:
Assumptions are described as the direction/premise towards a particular conclusion made by the speaker or author as these reflect the uninvestigated belief or a proposition without evidence that may or may not be true.
In the given argument, option C displays the assumption that the Kitchen magazine must have assumed without examining its validity and reached the conclusion that 'kitchen can collect its licensing fees....without endangering..other revenues'. Thus, option C is the correct answer.
