- D. 1, 2 and 3
Answer: B
Explanation
Statement 1 is incorrect. Production of algal biofuel is possible both in seas and on continents. They can grow on marginal or non-crop land and also on brackish or polluted water. Land based systems are more developed then sea based systems. Statements 2 and 3 are correct. Developing and engineering ABB technology requires a high level of expertise until construction is finished. Innovation for higher productivity also requires some knowledge and/or experience. All Algal based biofuel concepts require significant capital investment. Access to this technology by the poor may be difficult. Large-scale facilities are more economically viable, but are also more likely to have higher social and ecological impacts.
