Final answer:
The off-field actions of a player can affect fan trust and ticket sales.
Step-by-step explanation:
The off-field actions of a player can affect the willingness of fans to buy tickets to future games based on the development of fan trust among the team's fan base.
If a player on the team is arrested for domestic violence and it receives significant media attention, fans may lose trust in the team and its players. This loss of trust can lead to a decrease in ticket sales as fans may be less inclined to support a team that includes players with a history of off-field misconduct.
Therefore, the correct answer is D. Fan trust.
