Non-applying dependants - Citizenship - eta one more question - sorry!

Hello! I'm nearly done with the citizenship/naturalisation Application but one question I'm unsure of:

Non-applying dependants
---Do you have any dependants not applying with you at this time?(Required)
Yes
 No

I have 3 children but they are UKCs. Do I say Yes?

Apologies if has been asked before, I tried to use search function but all posts were quite dated

ETA one additional Question:

Trips outside the UK

When did you first arrive in the UK? Is this the first time I entered as a Visa-holder / i.e. 5 years ago? Or when I came as a tourist when I was visiting a friend in Uni here? First time ever or first time as part of all this process? Thanks

Also I think I know the answer, but will I need to do another biometrics if I just did one last week for ILR 

I would say yes and if it asks anything else, say they are British citizens.

Yes, you get to do biometrics again (it's to verify that the person who has ILR is the one applying for citizenship)

OK thank you @KFdancer - Apologies but I edited my original post w/ one more question - you were too quick Can you answer the one about 'first arrive' in UK?

Yes, I would use the date you entered on your current visa path.  I think there is a section where it asks about previous/other travel but they do change the form frequently so they may not ask.

OK, thank you so much! For everything! - can't believe I'm in the home stretch of this. A little walk down memory lane filling out all my other visa application dates and details.

This one will feel far too easy in comparison.
