Why each option
This scenario describes a two-tier application architecture where the client (locally installed application) directly communicates with the database server without an intermediary application server.
A one-tier architecture means the application, business logic, and data all reside on the same machine, which is not the case here with a separate database server.
In a two-tier architecture, the client (presentation and business logic) communicates directly with the data tier (database server). Here, the local application acts as the client, and it connects directly to the database server.
A three-tier architecture introduces an intermediate application server between the client and the database server, which is not present in this direct connection.
A four-tier architecture typically extends three-tier with an additional tier, perhaps for enterprise integration or caching, which is more complex than the described setup.
