Question

Protein and oil content of soybean is ________% and ________%, respectively.

• A. 43 and 20
• B. 35 and 30
• C. 30 and 35
• D. 20 and 43

Hint:

Soybean is known as a high protein oilseed, with protein content running close to double its oil content.

Answer 1

The Correct Option is A

This question tests a straight recall fact about soybean seed composition, comparing its protein share against its oil share.

1. 43 and 20: Soybean seed is well known to carry about 40 to 43 percent protein and about 18 to 20 percent oil, which is exactly why soybean is prized as both a protein meal source and an oilseed.
2. 35 and 30: This would put protein and oil almost on par with each other, but soybean protein is clearly and consistently much higher than its oil share, so this pairing does not fit.
3. 30 and 35: This wrongly makes oil the larger fraction, which never happens in soybean since protein always exceeds oil in the seed.
4. 20 and 43: This pairing swaps the two values completely, giving oil the higher number, which contradicts the basic identity of soybean as a protein rich crop.

Since soybean seed is documented to hold close to 43 percent protein alongside about 20 percent oil, the first pairing is the only one consistent with real seed analysis data.

Let's summarize:

• Soybean protein content is roughly double its oil content.
• Any option that makes oil equal to or greater than protein cannot describe soybean.

So the correct answer is 43% protein and 20% oil.
