Which of the following is the BEST indication of effective IT-business strategic alignment?

Active involvement of business management in IT strategy development ensures that IT initiatives are directly linked to and support the overarching business objectives and strategic direction, fostering true alignment rather than mere support. This collaborative approach integrates IT as a core strategic enabler from the outset, rather than an afterthought.

IT senior management reporting to the board indicates governance and accountability, but doesn't necessarily mean IT strategy is aligned with business strategy, just that it's being overseen.

Documenting business strategy to aid IT architecture design is a good practice for efficiency, but it's a reactive response rather than proactive involvement in strategic alignment.

A strategy focused solely on IT cost reduction, even with collaboration, may not fully align with broader business growth, innovation, or market expansion goals.
