I think the idea here is that each of the four witnesses gave one of the numbers in the question.

They all agree that it is 3*J*Z.

3 witnesses (all except A) agree that the second digit was 5.

3 witnesses (all except B) agree that the third digit was 1.

3 witnesses (all except C) agree that the second letter was an R.

Every letter/number that D gives is corroborated by two other witnesses (though a different two each time), so D is most likely to be correct.

I think you're right about the intention. However, I think a fairer deduction to draw from this is it proves any individual is quite likely to be wrong so you can't derive anything meaningful.
