Which of the following is a requirement for someone to be a director?

A key requirement for someone to serve as a director is that they must not be disqualified from holding office. This disqualification can arise from various circumstances such as legal issues, bankruptcy, or previous misconduct in another corporate role. Ensuring that the individual is eligible and has the legal capacity to serve helps maintain the integrity and governance of the company.

While the other options present interesting qualifications, they are not universally mandated. For example, a director does not need to be a financial expert, although having financial knowledge can be beneficial. Similarly, prior management experience may enhance a director's effectiveness, but it is not a formal requirement. Lastly, ownership of shares in the company can align interests but is not a compulsory criterion for someone to qualify as a director. Therefore, the requirement of being legally qualified is fundamental to ensure the proper stewardship and accountability of the board.
