NestJS offers the @nestjs/typeorm module specifically to integrate TypeORM easily.

Which feature of TypeORM aligns with NestJS's use of decorators?

A Entity classes and decorators

B Raw SQL queries

C XML configuration files

D Manual connection management

TypeORM uses entity classes and decorators, matching NestJS's decorator-based design.

How does NestJS help manage TypeORM repositories?

A By requiring manual repository creation

B By disabling repository use

C By injecting repositories via dependency injection

D By using global variables
