Explanation:

- Groundnut seeds, commonly known as peanuts, are significant for their oil and protein content.

- Different scientific sources report varying compositions. However, the typical range is well-studied.

- Option 1 offers 20 oil, 39 protein. This is unusual for groundnuts, which typically have higher oil content.

- Option 2 suggests 45 oil, 26 protein. This aligns well with common findings, as groundnut seeds are known for high oil and reasonable protein content.

- Option 3 lists 35 oil, 14 protein. The oil content seems slightly low for groundnuts.

- Option 4 offers 56 oil, 30 protein. While high oil content is possible, the combination seems off for groundnuts.

- Option 5 has 31 oil, 10 protein. Both numbers are on the lower side for groundnut characteristics.

- Option 2 ( 45 oil, 26 protein) closely reflects typical groundnut seed composition.
