Angular doubt???

help me find answer of this question Question: find error(s) in code mention in image assume all library has been loaded option: 1 errorMessage is declared/used twice

2 Constructor should not be empty

3 Service has not been injected properly into the application

4 There is no error. This code will work just fine.

5 Angular bundles can be created while writing the application as well. The application doesn’t necessarily need to be complete for them to work

6 All the external libraries are also bundled when ng build command is used. We don’t need to include them separately

7 Services are bundled separately from components in Angular prod build

8 None of the above statements are correct it will very helpfull.
