The correct answer is option 2 - Cattle and sheep. Foot and mouth disease is a highly contagious viral disease that affects cloven-hooved animals, such as cattle, sheep, goats, and pigs. It primarily affects livestock animals, including cattle and sheep, causing painful blisters and sores on their feet and mouths. The virus can be easily transmitted through direct contact with infected animals, their saliva, nasal discharge, or contaminated equipment and environment. Cattle and sheep can easily contract and spread the disease to other animals in their vicinity. While pigs are also susceptible to foot and mouth disease, the answer does not include them. Therefore, the correct answer is option 2 - Cattle and sheep. It is important to note that prompt detection and strict biosecurity measures are crucial in preventing the spread of this disease.
