Which choice would have the smallest impact on climate change when purchasing apples at the store? A. buying apples in large quantities to reduce trips to the store. B. buying apples from farms that plan to use organic practices. C. buying apples that have no packaging. D. buying apples that are locally grown.

The choice that would likely have the smallest impact on climate change when purchasing apples at the store is **A. buying apples in large quantities to reduce trips to the store**.

While reducing trips does save fuel, the overall impact in terms of carbon emissions might be relatively small compared to the other options. Options B (organic practices), C (no packaging), and D (local sourcing) can all have a more significant impact on reducing the environmental footprint associated with agricultural practices, food waste, and transportation emissions. Buying locally grown apples, for example, generally minimizes transportation emissions, which is a considerable factor in climate change. Organic farming practices often have lower greenhouse gas emissions compared to conventional farming and reduce the use of synthetic inputs. Packaging can also contribute to environmental impacts, especially if it's not recyclable or biodegradable.

Thus, while option A is beneficial, it is likely to have the least overall impact on climate change compared to the other choices.
