Premises:  

1. All engineers are intelligent → Engineers are a small circle inside the bigger "Intelligent" circle  

2. Some intelligent people are not doctors → There’s a part of "Intelligent" that’s outside "Doctors"

Conclusion I: Some engineers are not doctors  

Not necessarily. The "intelligent people who are not doctors" could all be artists, teachers, etc. Engineers might still all be doctors. So I doesn’t follow.

Conclusion II: All doctors are intelligent 

No info given about doctors. Some intelligent people aren’t doctors, but that says nothing about doctors being intelligent or not. So II doesn’t follow.

So from your options: Neither follows
