UK Standard Visitor Visa advice [closed]

I need advice, My uncle wants to apply for a standard tourist visa to visit the UK from India. He has fairly low income but has savings. But i plan on giving him the money for his flight ticket and will be covering any costs whilst he's here, i can provide proof with bank statements and payslips if required.

When filling in the form it asks for his income, savings ect. It then asks if anyone will be helping. I have put the entire cost of his trip coming to the UK will be covered by myself(Nephew), In the next question it asks why someone will be paying to cover his costs, how can i justify this?
