Leibniz, the seventeenth century philosopher, published his version of calculus before Newton did. But then Newton revealed his private notebooks, which showed he had been using these ideas for at least a decade before Leibniz's publication. Newton also claimed that he had disclosed these ideas to Leibniz in a letter shortly before Leibniz's publication. Yet close examination of the letter shows that Newton's few cryptic remarks did not reveal anything important about calculus. Thus, Leibniz and Newton each independently discovered calculus.

Which one of the following is an assumption on which the argument is based?

A) Leibniz did not tell anyone about calculus prior to publishing his version if it.

B) No third person independently discovered calculus prior to Newton and Leibniz.

C) Newton believed that Leibniz was able to learn something important about calculus from his letter to him.

D) Neither Newton nor Leibniz knew that the other had developed a version of calculus prior to Leibniz's publication.

E) Neither Leibniz nor Newton learned crucial details about calculus from some third source.

IMO - D

By method of negation
If both knew before publication then conclusion falls apart
Hence D is necessary assumption for conclusion to hold good

Kindly reveal the OA

IMHO E,
Try negating E. Which means Leibniz and Newton had learnt it from a third source and they did not independently discover calculus. This would break the conclusion.
