Concept:Crops are classified by their main economic product; here, the two plants are known for their oil content.
Explanation:Elaeis guineensis is the scientific name for the oil palm.
The oil palm is grown mainly for the oil extracted from its fruit.
Arachis hypogaea is the scientific name for groundnut, also called peanut.
Groundnut is a major source of vegetable oil.
Since both crops are cultivated chiefly for the oil they produce, they belong to the group called oil crops.
They are not fibre crops, as fibre crops provide materials like cotton or jute.
They are not fruit crops, because the commercial product is oil rather than fresh fruit.
They are not latex crops, because they do not produce rubber latex.
Therefore, both plants fit the category of oil crops.
Answer:B. oil crops
