Correct Answer: Wilhelm Conrad Rontgen
Solution : The correct option is Wilhelm Conrad Rontgen.
X-rays are used to detect any bone fractures and deformities and to examine the bone health of the body. In Wurzburg, Bavaria, physics professor Wilhelm Conrad Rontgen discovered X-rays in 1895. After seven weeks of diligent labour, during which he investigated the characteristics of this new sort of radiation capable of penetrating noticeably thick screens, he announced the discovery of X-rays. To emphasize that their nature was unknown, he gave them the term "X-rays".
