Those are called 'drop links' or 'stabilisers' .......... they connect the anti roll bar to the suspension struts. The ball joints on the ends may be worn, and they cause a knocking.
The anti roll bar is in fact the bottom bit......it has rubber bushes and steel brackets that couple it to the body shell.
I'll hazard a guess and say it's the anti roll bar bushes that are causing the issue here as they are D shaped, but we can't see one here!

I’ve seen worn anti-roll bar bushes in my time. Never seen one 'excessively' worn. When VOSA used to run refresher courses, the discussion on excessive wear always came up. The advice we were given was that the mot definition of 'excessive' wear was that it literally 'about to fail'. If you have the time and inclination, I’d appeal it.
On post 9, you can see the rubber bushes that secure the anti roll bar - I guess these are what they are talking about.
The other small stabilisers.......we can’t tell from here how worn they are.
