Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
docker exec -it myapp /bin/bash
Why this is correct
exec runs a new command in the running container; -it makes it interactive.

docker attach myapp
Why it's wrong here
attach connects to the main process, not spawn a new shell.
- ✗
docker run -it --name myapp myimage /bin/bash
Why it's wrong here
This would start a new container, not use the existing one.
- ✗
docker logs -f myapp
Why it's wrong here
logs shows output, not interactive shell.
