Answer:
D). Champollion eventually deciphered the first hieroglyphs, while Young did not.
Step-by-step explanation:
As per 'The Riddle of the Rosetta Stone', the careers of Thomas Young and Jean-Francois vary as 'Champollion gradually deciphered the first hieroglyphs, on the other hand Young failed to do so'. Even though they both are recognized as opponents yet in this aspect(deciphering the hieroglyphs of Rosetta stone) they are sardonically parallel as however Thomas Young began or accredited as the first to decipher or unravel the hieroglyphs of this stone(Rosetta stone) but he could not accomplish it completely. This research is further continued by Champollion who succeeded in concluding the work and advance(by deciphering) it completely(which Young could not). Thus, option D is the correct answer.
