to be engaged

Hello

Are these sentences correct?

  1. I want to know who was engaged in the project.
  2. I want to know when was he engaged in the project.
  3. I want to know if he was engaged in the project.

Thanks

Yes.

Though (2) would usually be written:
I want to know when he was engaged in the project.
(You don’t need he reverse word order of a direct question having used ‘I want to know…’)

Yes, you are correct. Sorry, I misread it.

I’ve been caught the same way more than once. More proof that the brain plays tricks when there is a pattern that you expect to see,
