Which SysML diagram type is a modification of the UML Class diagram?
A . Parametric Diagram
B. Internal Block Diagram
C. Package Diagram
D. Block Definition Diagram

Answer: D

Explanation:

The SysML diagram type that is a modification of the UML Class diagram is the Block Definition Diagram (BDD). A BDD shows the definition of blocks in terms of their features, such as properties, operations, ports, etc. It is similar to a UML Class diagram, but it adds some features specific to SysML, such as value types, units, flow properties, etc. A block is an extension of the UML Class metaclass that can be used to model any system component with structure and behavior.
