Step 1: Understanding the Concept:
Livestock plays a critical role in the Indian economy, providing livelihood support, food security, and draft power to millions of rural households.
National statistical reports (such as the Central Statistics Office and National Accounts Statistics) track the precise contribution of the livestock sector to agricultural output and the national Gross Domestic Product (GDP).
Step 2: Detailed Explanation:
Let us evaluate the statements using standard Indian economic data:
Statement (A) is correct.
The livestock sector contributes approximately \( 25\% \) to \( 30\% \) of the total value of output in the broader Agriculture, Forestry, and Fishing sector.
Specifically, standard national accounts data show its contribution is approximately \( 25.6\% \).
Statement (B) is correct.
The overall contribution of the livestock sector to India's total national Gross Value Added (GVA) GDP is approximately \( 4.11\% \), which represents a major share of rural economic activity.
Statement (C) is incorrect because a \( 50\% \) contribution is an overestimation of the livestock sector's share of agricultural output.
Statement (D) is incorrect because \( 15.11\% \) is much higher than the actual contribution of livestock to India's total national GDP.
Therefore, only statements (A) and (B) are correct.
Step 3: Final Answer:
The true statements regarding livestock's economic contribution are (A) and (B) only.
