IMO B for the below reasons.

A. Usage of infinitive is wrong here. Because it hints that the progress was made with an objective to understand and manipulate the molecule.
B. Correct
C/E. passive voice is not required and is incorrect here
D. 'have made' is required as the progress is still happening (usage of Since)
