Step 1: Understanding the Concept:
To correctly sequence these major Indian animal husbandry and livestock development programmes, we must identify their historical years of launching.
Step 2: Detailed Explanation:
Let us review the historical launch years of each listed program:
1. ICDP (Intensive Cattle Development Programme):
This program was launched during 1964-65 to provide a complete package of improved animal husbandry practices to cattle owners.
2. SLBP (Special Livestock Breeding Programme):
This developmental scheme was launched during 1975-76 to assist small/marginal farmers and agricultural laborers by establishing dairy, poultry, sheep, and piggery units.
3. NPDD (National Programme for Dairy Development):
This national program was designed and launched in February 2014 by merging older schemes to build a robust dairy infrastructure.
4. RGM (Rashtriya Gokul Mission):
This mission was launched in December 2014 to conserve and develop indigenous bovine breeds.
5. NADCP (National Animal Disease Control Programme):
This major disease control program was launched in September 2019 to control Foot and Mouth Disease (FMD) and Brucellosis in livestock.
Arranging these programs chronologically from earliest to most recent:
\[ \text{ICDP (1964)} \rightarrow \text{SLBP (1975)} \rightarrow \text{NPDD (Feb 2014)} \rightarrow \text{RGM (Dec 2014)} \rightarrow \text{NADCP (2019)} \]
This matches the sequence in option 2.
Step 3: Final Answer:
The correct chronological order is option 2.
