Struggling filling MN1 form

Hi guys,
Please can anyone help ?
I'm starting filling MN1 form and I'm struggling on questions (apply for my son)
1 section 1 personnel information
1.1) Please indicate the section of British nationality Act 1981 under which you would like to application considered.
Answer: section 3(1) ? (I'm British through naturalisation and ILE for my son visa)

Section 3- Parent Residence
3.1) Please say which parent is the one is a British citizen by decent and on whom this application is base
Mother. Father.

I shall leave This section right? As I'm get British through naturalisation?

Thanks in advance

1. If the child was born abroad then it is under section 3(1) of the nationality act, which I am assuming your child is.

2. Question 3.1 is not relevant to you/child.

Thanks for your replied:)
