Answer:
Option B
Step-by-step explanation:
Terminology: Abiotic means something non-living.
A) Plants (referring to 'weedy plants') are organisms, so they do not fit the criteria of being an abiotic factor that controls the population of the bean plant.
B) Sunlight is an abiotic factor since it is a non-living thing.
C) Squirrels are living organisms, so they do not count as an abiotic factor.
We can conclude that option B describes a population depending on an abiotic factor.
