I've been running Exam Simulation with both IIL PMIQ and Crosswind. They disagree on who often help resolve disagreement on resource assignment and project scope between Project Manager and Line Manager.

PMIQ thinks that the conflict/disagreement are often resolved by the Sponsor, while Crosswind says that it is Senior Management.

In PMP Exam, in the question, if there are both options, Sponsor, and Senior Management, which one is the correct answer to PMI?

Yours,
