Hi. You did not enter the text to which this question refers, which makes it impossible for it to be answered. However, I will try to help you as best I can.
"Engetter" is a word of French origin, which refers to the rejection and expulsion of something or someone. It is likely that in the text to which your question refers, this word has been placed with this meaning, to be sure of this, you should rewrite the sentence by changing the word "engetter" to its meanings and making sure the sentence is coherent. You can also see this by looking at the context of the sentence as a whole and identifying whether that context has something that is being kicked out or rejected.

Your answer should be WHO.
Think of it like this: You wouldn't say "The boy it (a variant of 'which')", because it simply just sounds odd. Instead, you're wired to think "The boy, he (an unknown name, so it would be 'who')".
