Final answer:
An increase in consumer desire for strawberries is most likely to result in an increase in the number of strawberry pickers.
Step-by-step explanation:
When there is an increase in consumer desire for strawberries, it is most likely to result in option C: an increase in the number of strawberry pickers. This is because a higher demand for strawberries means that more strawberries need to be picked in order to meet the increased consumer demand. This would lead to an increased number of people picking strawberries to ensure a sufficient supply.
