Ancestry Visa Renewal - declaring income

So I work two part time jobs, one of which I only started in June - but the application asks “What is the annual income.” Do I put down (a) What I’ve earned since I started, although this does not represent what I will earn in a tax year, (b) calculate what the annual income would be for a tax year, or (c) income until the end of this tax year, ie April?

Thanks for the wisdom, can’t find any answers on this one myself
