Which of the following symbols in an activity diagram could be confusing when differentiating between synchronization and decision points?Mark(3 Marks)(Choose one option)ForkMerge NodeJoinDecision Node

The symbol in an activity diagram that could be confusing when differentiating between synchronization and decision points is the Fork. This is because both the Fork and Decision Node use a similar symbol (a horizontal or vertical bar), which can lead to confusion. The Fork is used for synchronization (splitting a single flow into multiple concurrent flows), while the Decision Node is used for making decisions (splitting a single flow into multiple alternative flows based on conditions). However, their similar appearance can make it difficult to distinguish between them.
