Concept:Mixed farming combines crop production with animal rearing on the same farm.
Explanation:In mixed farming, the farmer keeps livestock alongside growing crops.
If drought, pests, or disease destroy the crops, the farmer can sell animals, meat, eggs, or milk to earn income and feed the family.
Thus, animals act as a safety net when the harvest fails.
Crop rotation involves growing different crops in sequence and does not include animals.
Organic farming avoids synthetic chemicals but does not necessarily keep livestock as a fallback.
Mixed cropping grows two or more crops together on the same field, but still has no animals.
Answer:B. Mixed farming.
