What is the most important similarity in the achievements of Evelyn and Bismillah Khan?

Both broke limited beliefs through art

The governing concept is achievement through perseverance and artistic excellence. Evelyn Glennie challenged the belief that profound hearing loss must prevent a person from becoming a successful musician. Through disciplined training, she learned to perceive musical vibrations through different parts of her body and became an acclaimed percussionist. Bismillah Khan similarly challenged the narrow view that the shehnai was only a traditional or ceremonial instrument. Through lifelong practice, he brought it to the classical concert stage and earned national and international respect. Therefore, option A is correct: both transformed restrictive assumptions through art. Options B, C, and D contradict the text because neither abandoned music, relied only on luck, nor rejected guidance.
