Stuck on question 14 , Moving Around

I am unable to walk over 20 metres, repeatedly, because of pain, fatigue and breathlessness , symptoms of rheumatoid arthritis. A walking aid ( stick, crutches, ), does not help because of the above symptoms of RA. Same for wheelchair. I always walk with a limp, due to constant pain in my Right Hip, symptom of RA. Does one have to cover all scenarios , like supermarket plus length of time in supermarket ( 30 ) mins max, as really struggle and always have to stop and sit down on s/m floor, ( even outside on ground when no wall or bench ), mainly due to fatigue and breathlessness for 4-5 minutes before using shelving as support to get up - plus always use shopping trolley as “ an aid “, support by resting my forearms on trolley as lessen pain and fatigue .Use self serve as not able to stand in que, so sit on floor while using cash til . Does this count ? Carry bags to car over my forearms. ( recently been awarded Blue Badge ). Does this count ? Does “ Moving Around “ require how one gets up and down stairs and moving around kitchen. ( I spend 80% daily lead on sofa due to fatigue)
Is this enough ? What have I missed out ? Many Thanks, J.

Many Thanks for bringing my attention to this Gordon , going to change to C. ( can stand and move unaided more than 20 metres, but no more than 50 metres ), including having to stop and rest , due to fatigue, pain and breathlessness. As this is more accurate, but struggle to stand on one spot more than one minute ; have to move or sit down, Is this enough to award me any points ?
Many Thanks Again , J.
