Which development model should the architect recommend to be used by the consolidated development team?

Universal Containers CUC) has developed extensions of Salesforce Service Cloud for the use of its customer service teams using the change set development model.

Recently, UC acquired a company that develops extensions of an AppExchange app. The development team of the acquired company uses the org development model. The Universal Containers CTO wants both teams to work on a single org and follow the same set of processes.

Which development model should the architect recommend to be used by the consolidated development team?
A . Org development model, because the acquired company’s team is already using it, and it is better than the change set development model.
B. Package development model, because it allows packages to be created and deployed using declarative (point-and-click) development tools, without writing code.
C. Package development model, so teams can build release artifacts that can be tested and released independently from artifacts for other projects.
D. Change set development model, because UC is already using it, so it will face less resistance.
