Trait B decreased in frequency over time. So, the correct option is A.

A trait is an attribute or characteristic of an organism that is influenced by its genes, according to genetics. Behavioural and physical characteristics, including intelligence and friendliness, can be altered by a combination of hereditary and environmental variables.

A trait is a distinctive quality or attribute that can be acquired by environmental circumstances, genetic inheritance, or both. In biology, traits are observable and quantifiable qualities of an organism, including its physical characteristics, behaviour, and other traits. For instance, physical characteristics like eye colour, height, and hair texture can all be passed on through genetics.

Hence, the correct option is A.
