The number of epipedons commonly found in India is

Correct option is A

The correct answer is (A) 3

Explanation:
• While there are technically 8-9 diagnostic surface horizons (epipedons) recognized in the USDA Soil Taxonomy (such as Mollic, Umbric, Ochric, Histic, Melanic, Anthropic, Plaggen, etc.), only a few are common in the diverse landscapes of India.
• The three most commonly found epipedons in India are: 1. Ochric: The most widespread, found in arid and semi-arid regions (light-colored, low organic matter). 2. Mollic: Found in some fertile alluvial soils and grasslands. 3. Umbric: Found in high-rainfall areas like the Western Ghats or North-East India (dark but acidic).
• Some sources also include Histic in localized peaty/marshy areas (like Kerala's 'Karri' soils), but the primary classification used in major Indian soil studies often highlights these three main types.

Information Booster:
• Most Indian soils are classified under the orders Inceptisols, Entisols, and Alfisols, which predominantly feature the Ochric epipedon.
• Black soils (Vertisols) typically have an Ochric or Mollic epipedon.

Additional Knowledge:
• 8 (Option B): Represents the total number of recognized epipedons in some versions of Soil Taxonomy (Mollic, Umbric, Anthropic, Plaggen, Ochric, Histic, Melanic, Folistic).
• 9: Some newer classifications add more specific types like the 'Salic' epipedon in certain contexts, but this is less common.
