In 1871, Charles Darwin published The Descent of Man, and before that, Gregor Mendel already had discovered the principles of genetics, using his famous pea plant experiments, and ultimately they would explain and justify Darwin’s conclusions.

Hello Mike ,
Original Sentence says principles of genetics was discovered using pea plant experiments
whereas B says during the pea plant experiments ; doesnt this alter the meaning of the sentence ??

Dear rohitkumar77,Original Sentence says principles of genetics was discovered using pea plant experiments

I'm happy to respond.
Think about what a scientific experiment is. The scientist has a question about something currently unknown, then she sets up an experiment to observe what happens on special conditions. A discovery may happen during the actual course of the experiment, "on the spot," or if the data or patterns are complicated, it may take time to process the data before one has a discovery. For practical purposes, both the time in the lab with the experimental design and the time afterwards in one's office processing all that data on a computer could both be called "during the experiment." To draw a distinction between those would be splitting hairs in a way that the GMAT does not do.
By contrast, "using the experiment" is an awkward formulation. In some sense, this is a sloppy colloquial formulation. We get the sense of what the author is trying to say, but technically, what does it mean to "use" an experiment? It's an extremely odd phrasing. Presumably, it means to learn or understand something from the data, and of course this learning happened "during the experiment." It's not really clear what kind of "using" one would do besides this.
Insofar as we can discern the meaning in (A), choice (B) formulates it more clearly.
Does this make sense?
Mike
