Which of the following is NOT a primary crop in Pennsylvania?

Cotton is not considered a primary crop in Pennsylvania due to the state's climate and soil conditions, which are not conducive to cotton cultivation. Pennsylvania has a temperate climate with colder winters and shorter growing seasons compared to the warmer, longer seasons found in the Southern states where cotton is predominantly grown.

In contrast, apples, corn, and tobacco are significant crops within Pennsylvania. The state is one of the leading producers of apples and corn, benefiting from its suitable growing conditions. Tobacco, while not as prominent as it once was, has historical significance as a crop in Pennsylvania. Overall, the agricultural focus in Pennsylvania aligns more closely with crops that thrive in its specific environmental conditions, making cotton an outlier among the options listed.
