Housewife Finance Question for UK Visit visa

[mosuliman]

Hi,

I am applying for UK visit visa for my mother, which is a housewife with no income and no savings. My mother is living with my father, who is covering all her day-to-day expenses and will also be fully sponsoring her trip to the UK. During the application process, I came through the following question:

Do you have another income or any savings? The options are:

1- Other regular income:

A-Allowance or regular money from your family
B-Pension
C-Investments
D-Another income.

2- Savings

3- I do not have any other income or savings

My question is: Should I select option (3), or should I use option (1) and declare my father's income and later say in the additional information part that this is my father's income.

Many thanks.
