In any form of chromatography, how will a compound which interacts more strongly with the stationary phase elute compared to one that interacts less strongly?
A) A compound interacting more strongly will elute earlier than one with weaker interactions.
B) A compound interacting more strongly will elute later than one with weaker interactions.
C) The order of elution has nothing to do with interactions with the stationary phase, but with interactions with the mobile phase.
