Choose the correct answer:What is wrong with this BPMN diagram?

In the given diagram:

After activityA, there is anexclusive gateway(with conditionscond1andcond2), soeither B or Cis chosen—never both.

AfterBandC, their flows go into a gateway with aplus sign, which is aParallel Gateway (AND-join)in BPMN.

AParallel Joinwaits fora token fromeveryincoming branchbefore it can release a token onward toD. But due to the earlier exclusive split,only oneof the two branches (B or C) ever receives a token. The other branch never activates, so the parallel join never gets all required tokens.

Consequences:

The join gateway willnever be satisfied,

Therefore, the flownever proceeds to activity D.

So the defect is exactly what optionBsays:

The activity D can never be reached.

That is the correct answer.
