Best answer
The correct option is (a) Stevens

Explanation: Stevens was the scientist who first discovered Y-chromosome. Many scientists concluded that the ‘X body’ which was discovered by Henking was a chromosome. Therefore, in 1905, X and Y chromosomes were named as sex chromosomes by Stevens and Wilson.
