How can two students perform chromatography on the same mixture, observe that the colored samples all move different distances, and still correctly identify the components?

(a) Each student analyzes the mixture using a different type of chromatography, resulting in distinct separation patterns.

(b) The students utilize different eluent mixtures, causing the components to migrate at varying rates.

(c) The students employ different stationary phases, leading to unique interactions with the components and diverse elution patterns.

(d) Each student applies a different concentration of the sample solution, affecting the separation distances of the components.
