Correct Option: B

Soybean is a significant and cheap source of protein for animal feeds and many prepackaged meals. Soybeans produce significantly more protein per acre than most other uses of land. The beans contain significant amounts of phytic acid, alpha-linolenic acid, and isoflavones. Together, soybean oil and protein content account for about 60% of dry soybeans by weight (protein at 40% and oil at 20%). The remainder consists of 35% carbohydrate and about 5% ash.
