Answer

Brief Explanations:

The paragraph discusses different algae farm designs and their requirements. Sentence 14 mentions "different farms might feature different designs", and the added sentence about algae biofuel being a recent technology that needs to establish itself logically follows after introducing the variety of farm designs (sentence 14). It then leads into the discussion about the challenges (like investors not easily persuaded) in the subsequent sentences.

Answer:

A. After sentence 14
