Answer: Option D
:
D
Many would have felt that option (a) is correct. But that is not the case. Read through the lines.
He says that the sensitivity test used is not counter-factual ("Obviously is itself not counterfactual").
But in the next line he states that "but he is basing his assessment partly on his knowledge of the past".
And in the last line the author states that "This too is counter-factualism" which means that the court also uses Counter-factualism like the businessman.
Option (b) and (c) are definitely true.
So the answer is option (d).
