Lacra D is once more quite hard to make out. Burl mentioned a large slab lying in the centre of the circle which was the deciding factor in identifying it. This circle was the subject of excavations, and a late bronze age urn was found. It can now be seen in the museum in Barrow.
The rows at Lacra D are listed as questionable but, we could make out this line easily enough. Of course there are more reasons than just neolithic ones for rocks to lie in a line, including mental ones, but here is a picture, and you can make up your own mind.
