children application MN1

[krus2]

Hello
I need some help.
I come from Poland and i already got british citizenship 2 months ago.
I live in Uk 8 years together with my polish wife.
She never work here and she is looking after our kids.
Now I would like to apply for my daughters british citizenship.
I know i need form mn1, my one daughter is also 8 years in Uk and now she is 10 years old, my second daughter was born in uk and she is now 6.
Should i apply in section 1(3) or 3(1). Will they get british citizenship?
Thank you.
