Apologies: Q93 has 2 correct answers E and D!
E is proven correct (gold used as prosthetic teeth centuries ago, and as other prosthetics eg as weight for upper eyelids that wont close as in Bell's Palsy); but D is so far has not been proven to be wrong (so far, no reports have shown 2 identical sets of teeth profiles found in 2 different individuals). So D is also correct.
As to which is the ''More Correct'' one and thus deserving FCA & Correct Answer, I am not able to find a solution to say one is more correct than the other, and I will understand if forumers feel that E should be ''more correct''. My argument is that it is possible that one day, an individual will be found to have developed an inflammation to pure gold (please note that the current ''Gold Allergy'' is basically due to impurities in gold jewelleries eg to Nickel, Palladium and various other metals in the gold jewelleries).
A) is wrong as teeth is not considered a bone; enamel in a tooth is Hydroxyapatite, a mineral of Calcium
B) enamel in teeth is the hardest part of our body, scoring at 5 on Moh's score (diamond scores 10); enamel is actually harder than steel but enamel shatters easier
C) enamel has no blood supply so it doesnt heal like like bones
D) & E) see above
