Of the given statements, the one least likely to be used to describe variation is Variations that decrease reproductive success are more likely to be passed on.
Option B is correct
The fundamental principle of natural selection states that variations providing advantages in survival and reproduction are more likely to be passed on, influencing future generations. Also we can say, variations that decrease reproductive success would naturally be less likely to be passed on as they hinder the individual's ability to leave offspring.
Therefore, stating that variations with negative impacts are more likely to be passed on contradicts the basic principles of evolution and is unrealistic.

Variations are inherited differences between individuals of the same species.
Variations that decrease reproductive success are more likely to be passed on.
Variations may result in changes to an entire population after many generations.
