I'm just glad the question didn't ask about the CMD instruction. That one always trips me up!

C and D are the way to go. I'm surprised that option E has 'World*' instead of 'World'. That's a bit of a giveaway that it's not correct.

I was a bit confused at first, but now I see that C and D are the way to go. The exec form is the way to go for ENTRYPOINT.

Yes, using the exec form with an array is the best practice for ENTRYPOINT.

I'm not sure, but I think option B) ENTRYPOINT [ \'echo hello world\' ] could also work.

I agree with Dusti. C and D are the correct answers. The other options don't use the exec form or don't properly split the command.

I agree, D is also correct because it uses the exec form.

I think option C) ENTRYPOINT [ \'echo\', \'hello\', \'world\' ] would output hello world.

I think the correct answers are C and D. The ENTRYPOINT instruction in a Dockerfile should be in the exec form, which is a JSON array, and the command should be split into individual elements.
