Explanation:

Here’s the thing—when it comes to draught-purpose cattle, we’re talking about breeds mainly used for heavy work like ploughing or carting, not milk production.

- Amritmahal: Known for strength. Classic draught breed from Karnataka.

- Malvi: Strong, found in Madhya Pradesh, mainly for draught work.

- Kangayam: Tamil Nadu’s pride, famous for pulling loads and farm work.

- Sahiwal: This one stands out—primarily a dairy breed, famed for its rich milk, not really used for heavy load-pulling. This is the odd one out.

- Nagori: Rajasthan’s traditional draught cattle, valued for their stamina.

So, your answer is option:4- Sahiwal.
