It's a long form and you need to really really answer the question. This is more important than medical evidence.
So if it says 'can you make a meal?' Your answer should be something like 'I need prompting to remind me when mealtimes are. I can't stand by the cooker due to breathlessness and need to sit and rest after 5 minutes. I can't carry a saucepan due to pain so my partner does it. I need supervision when switching the gas on as I don't remember to switch it off etc etc etc'
Not 'yes' because you can microwave a Ready meal.
Whatever the disability is, it needs spelling out step by step to answer the question.
They care about how the diagnosis affects function, not what the diagnosis is or how sad it makes you.
