Answer: (a).No difference, they both denote properties of a class Explanation:In UML, there is technically no difference between an attribute and an association. They both denote properties of a class and can be used to model the properties of a class. However, in practice, it is common to model simple properties such as numbers and dates as attributes and more significant concepts as associations.
