(D) Ethylene
Choose the correct answer from the options given below:

• (A) and (D) only
• (A) and (B) only
• (B) and (C) only
• (A) only

Answer 1

The Correct Option is B

The correct answer is (2) (A) and (C) only.

Forage crops are plants that are grown specifically to be used as feed for livestock. These crops are usually high in nutrients and provide the necessary food for animals, particularly herbivores.

Let's break down the options:

(A) Berseem: Berseem is a forage crop. It is a type of clover used as fodder for livestock.

(B) Safflower: Safflower is not a forage crop. It is mainly grown for its seeds, which are used for oil production, and it is not used as livestock feed.

(C) Lucerne: Lucerne, also known as alfalfa, is a forage crop. It is widely used as animal fodder, particularly for dairy cattle and other livestock.

(D) Sunflower: Sunflower is not a forage crop. It is grown for its seeds, which are used for oil extraction and as food, but not primarily for animal feed.

Thus, Berseem and Lucerne are forage crops, so the correct answer is (2) (A) and (C) only.

Answer 2

Berseem and Lucerne are classified as forage crops, which are cultivated primarily for feeding livestock. Safflower and sunflower are not generally considered forage crops.
