Explanation

It is critical to work out here whether the physicists mentioned at the end of the sentence were for or against Einstein’s theory. You know that the idea went from “purely experiential” to “theoretically” something.

There’s a contrast here, and the contrast is not between right and wrong. It is between something that has been shown by experiment and something that has been understood theoretically. This means the later scientists are providing support for Einstein. Undermined and sabotaged are negative, while condoned and pardoned don’t make much sense. Only bolstered and buttressed correctly express the idea of
support.

Hence options bolstered, buttressed are best fit!
