Information required for MN1 Registration for a 10 month old baby

Hi Members.

I recently got my ILR now and i am applying for the naturalisation of my son registration who is 10 month using MN1 registration, He was born before I was settled.

I have a few questions which I was hoping someone can answer kindly.

1. On the online form that I am filling in the application on behalf of my son what should i put under who does the email belong to

The applicant
An immigration adviser based in UK
Someone Else (I think it is this option as I am filoing the application my son's behalf)

2. When asked when did yiu start living at thr address i put March 2019 as he was born in March, on the next spot it asks on have you lived at your current adresss for 5 years Shall i put Yes or No.

If i put No it ask for Previous Adresses but my son is 10 month old and doea not have a Previous Adresss. Shall i put Yes

3.When asked for Nationality what should i put as he was born here but I am from Pakistan. Shall I put UK or Pakistan

I will appreciate your response

Regards,
Muhammad
