The correct answer is 'Insider threat' because the employee who is part of the organization, had access to sensitive data and abused that access to provide information to a competitor, typically for personal gain or due to a grievance. 'Nation-state' would not usually target a company for product designs unless it has national security implications. An 'Unskilled attacker' is less likely to have specific internal knowledge about the organization's confidential projects. 'Organized crime' groups generally target financial gain through more direct means such as extortion or large scale data breaches for credit card information.
