A. In what promises to be an alternative to corneal transplantation in treating blindness caused from damage to cornea, scientists from city-based L.V. Prasad Eye Institute (LVPEI) in collaboration with U.S. scientists claimed to have discovered potent stem cells in the eye that possess the ability to restore lost sight.
B. In what promises to be an alternative to corneal transplantation for treating blindness caused from damage to cornea, the discovery of potent stem cells in the eye by scientists from city-based L.V.

C. In what promises to be an alternative to corneal transplantation for treating blindness caused from damage to cornea, the discovery of potent stem cells possessing the ability to restore lost sight in the eye by city-based L.V. Prasad Eye Institute (LVPEI)’s scientists along with U.S. scientists, offers hope.
D. Scientists from city-based L.V. Prasad Eye Institute (LVPEI) in collaboration with U.S. scientists claimed to have discovered potent stem cells in the eye, which possess the ability to restore lost sight, and promising to be an alternative to corneal transplantation in treating blindness caused from damage to cornea.
E. Scientists from city-based L.V. Prasad Eye Institute (LVPEI) in collaboration with U.S. scientists claimed to have discovered potent stem cells in the eye that possess the ability to restore lost sight promising to be an alternative to corneal transplantation in treating blindness caused from damage to cornea.
Let me try to explain, although I rarely post anything.
I am trying to explain each answer choice.
1) In what promises to be an alternative to corneal transplantation in treating blindness..................., scientists from city-based ................
here opening of the sentence seems to modify scientists, but scientists are not promising anything. It is Discovery that is promising. So wrong.
2) In what promises to be an alternative....................,
the discovery of potent stem cells..............................
possess the ability to.................
Opening seems to modify the discovery of cells - correct, after that there is subject-verb mismatch. It should have been, the discovery of........possesses... So wrong
3) This is correct answer choice. Opening modifies discovery of stem cells...and verb is ...offers hope.
4) potent stem cells in the eye,
which this seems to suggest eye possess the ability, wrong choice.
5) discovered potent stem cells in the eye
that possess the ability to restore lost sight
promising to be an alternative
here "that" seems to point to "eye", even if we ignore and think it might be referring to stem cells (as there are few examples in which "that" can refer a little backward) but as we move forward we have another confusion, " lost sight promising", lost sight is not promising. as this is verb-ing and it refers to subject immediately before it. another confusion ---- wrong choice.
so answer is C
