which of the following is not an example of a fruit?\na: raspberries\nb: sunflower seeds\nc: corn\nd: potato

Brief Explanations:

In botanical terms, a fruit is the seed-bearing structure in flowering plants formed from the ovary after flowering. Raspberries are aggregate fruits. Corn kernels and sunflower seeds are technically dry, indehiscent fruits (specifically caryopses and achenes, respectively) because they develop from the ovary and contain the seed. A potato, however, is a botanical tuber, which is a modified underground storage stem, not a product of the plant's reproductive ovary.

Answer:

D. Potato
