Pip mandatory reconsideration

I'm requesting a mandatory reconsideration, I'm just wondering when choosing the descriptor I believe I meet, will the assessor discount me meeting any because I've chosen a high scoring descriptor or will they choose a lower scoring one if they believe I meet one.

I was receiving standard rate for both standard living and mobility, They stopped both after my review even though I have new and worsening conditions. Saying I can prepare an cook a meal unaided, when I use a crutch and stool for sciatica, venous insufficiency, edema and slipped disc. States I said I can stand and mobilise for 20 minutes, I did not, I said I could not sit or stand for 20 minutes. Used the same for mobility. I'm housebound due to severe anxiety and agoraphobia, and aware they can only judge mobility outside of the home. I also know you can't satisfy planning and following a journey option d and f for anxiety or agoraphobia, only cognitive reasons. leaving option e or b. And option e only considered for severe agoraphobia or cognitive impairment. So wondering if I should say option e or b based on likely outcome. I have mental health referrals an lots of gp evidence of being housebound.
