If you are applying for a minor who's a family member (e.g., your child), and the minor will be staying with you at the address you stated in the child's application, then the answer is the minor is staying with father, or whatever your relationship is.
As @Traveller notes in the comments: Part 7 of the UK Visa Guidance instructs applicants to write the [child's or children's] names and GWF numbers for the parents in Part 7 of the child's application, and make an additional note in Part 9.
