The correct answer is D. Both A and C
Explanation:
In biology, a phenotype refers to a trait or characteristic that is observable in an organism, including physical characteristics, physiological characteristics, and behavioral characteristics. The phenotype is the result of the expression of genes or environmental factors. Considering this, both "a certain duck has a blue beak" and "most cheetahs live solitary lives" are phenotypes because they are traits that can be observed in terms of morphology or physical characteristics in the case of the duck or in terms of behavior in the case of the cheetah. On the other hand, a mutation is not necessarily a phenotype except if it is expressed.
More waste has been a negative impact of technology, as more human labor is not a bad thing as it employs people and earns them money to support themselves and their families. Less farming and less access to food are not a direct effect of technology; in fact, technology improves farming and allows more crop yield. Hope this helps! :)

I'd say C, because the experiment would consist of cutting the tall plant to see if the trait of now being short (which is actually not a trait, you can't change genes like that, cutting the plant does not alter DNA or genes in any way.). So that would result in controlling for the plant's experiences before pollination. (does that make sense?) Basically they're testing for the plant's ability to pass on its life experiences to its offsprings.
