===========
The EC-Council CCISO program defines RACI as a governance and accountability model standing for Responsible, Accountable, Consulted, and Informed. CCISO documentation emphasizes that RACI matrices are critical for clarifying ownership, decision authority, and communication paths within security programs and enterprise initiatives.
“Responsible” identifies who performs the work, while “Accountable” designates the single individual ultimately answerable for outcomes. “Consulted” parties provide input or expertise, and “Informed” stakeholders are kept aware of progress or decisions. CCISO materials stress that proper use of RACI reduces confusion, eliminates duplicated effort, and strengthens executive oversight.
Other options either misrepresent governance terminology or omit accountability, which CCISO explicitly identifies as essential for security leadership. Therefore, Option B is correct.
