ANSWERS
1) All false except d.
2) a., b. & e. are true. c. & d. are false. The disc margins are slightly blurred. This is because they are out of focus. The retina is detached, so it is in front of the disc, which means either the disc or the retina will be out of focus in fundus photos of a retinal detachment.
3) All false except b.
