Solution

Break Down the Problem

  1. Identify the context of a systems sequence diagram.
  2. Understand what symbols indicate conditions (true/false) in such diagrams.
  3. Evaluate the options provided.

Relevant Concepts

  • In UML (Unified Modeling Language) sequence diagrams, conditions are typically represented by specific symbols that denote branching or alternatives in the flow of the system.

Analysis and Detail

  1. **Option a: / ** - This symbol is often used to indicate a guard condition for transitions in state diagrams, but not specifically in sequence diagrams.
  2. Option b: [ ] - Square brackets are commonly used to denote conditions in UML diagrams, including sequence diagrams. This is the format for specifying guards or conditions.
  3. Option c: { } - Curly braces might represent a set or grouping but are not standard for true/false conditions.
  4. **Option d: * ** - The asterisk is often used to represent repetition or iterations, not conditions.

Verify and Summarize

Upon analyzing the options, it is clear that option b: [ ] is the correct symbol used to indicate a true/false condition in systems sequence diagrams.

Final Answer

The correct symbol that indicates a true/false condition on a systems sequence diagram is b. [ ].
