The correct chronology of steps involved in the anaerobic digestion during the production of biogas is:

1. hydrolysis → acidogenesis → acetogenesis → methanogenesis.
2. hydrolysis → acetogenesis → acidogenesis → methanogenesis.
3. acetogenesis → acidogenesis → hydrolysis → methanogenesis.
4. acetogenesis → acidogenesis → methanogenesis → hydrolysis

Consider the given two statements:

I:  Methane and power produced in anaerobic digestion facilities can be used to replace energy derived from fossil fuels, and hence reduce emissions of greenhouse gases.
II:  In developing countries, simple home and farm-based anaerobic digestion systems offer the potential for low-cost energy for cooking and lighting.

1. Both I and II are correct and II explains I.
2. Both I and II are correct but II does not explain I.
3. I is correct and II is incorrect.
4. Both I and II are incorrect.

The figure shows the steps in production of biogas. Identify the options where the description given  are correct for the steps enumerated in the diagram:
I. Step 1 is hydrolysis where complex organic molecules are hydrolysed
II. Step 2 is acidogenesis where small organic molecules are converted to fatty acid
III. Step 3 is acetogenesis
IV. Step 4 is methanogenesis
Mark the correct option:
1. Only II and III 2. Only I, III and IV
3. Only I, II and IV 4. I, II, III and IV
