The diagram fragment that correctly shows a SysML Block extending a basic UML Class is Option B. This option shows a Block with the stereotype <> applied to it. This stereotype indicates that the Block is an extension of the Class metaclass. The Block inherits all the features of the Class, such as attributes, operations, associations, etc., and adds additional features specific to SysML, such as ports, flows, values, constraints, etc. References: https://www.omg.org/ocsmp/ocsmp-adv-exam.htm https://sysml.org/sysml-faq/what-is-block-definition-diagram.html
