It is possible to produce algae-based biofuels, but what is/are the likely limitation(s) of developing countries in promoting this industry? 1. Production of algae-based biofuels is possible in seas only and not on continents. 2. Setting up and engineering the algae-based biofuels production requires high level of expertise/technology until the construction is completed. 3. Economically viable production necessitates the setting up of large scale facilities which may raise ecological and social concerns. Select the correct answer using the code given below:

Select the correct answer using the code given below: Correct Answer 2 and 3 only
The correct answer is 2 and 3 only.
- Production of algae-based biofuels is possible on land or saline water or wastewater. So Statement 1 is incorrect.
- Production of algal biofuel is possible both in seas and on continents. They can grow on marginal or non-cropland and also on brackish or polluted water. Land-based systems are more developed than sea-based systems.
- Setting up and engineering the algae-based biofuels production requires a high level of expertise/technology until the construction is completed because producing biofuels from algae is still in a pre-commercial stage of technology development and capital investments, is a significant barrier. So Statement 2 is correct.
- Economically viable production necessitates the setting up of large scale facilities which may raise ecological and social concerns as it will reduce the amount of food available for humans and due to supply shortage it will increase the cost of food as well as the cost of fuel. So Statement 3 is correct.
