Correct Option (B)
The passage explicitly states that the issue of worldwide supply of food has gained significance because "in recent years, the capabilities individual countries to generate uninterrupted chain of food supplies have come under strain." This directly supports statement 3, which highlights the limitation in capabilities for sustained food supply as a key factor.
Incorrect Options:
Statement 1: The passage indicates that the "quantum and the composition of demand has been undergoing big changes," which could be influenced by population growth. However, it does not specifically identify "overgrowth of the population worldwide" as the primary reason for the increased importance of worldwide food supply. The emphasis is broader, encompassing changes in demand patterns and supply capabilities.
Statement 2: The passage mentions that "capabilities individual countries to generate uninterrupted chain of food supplies have come under strain," implying challenges in the supply chain, including production. However, it does not state that there has been a "sharp decline in the area of food production." The text refers to food production as a global issue, but not specifically a decline in area as the main cause for the issue gaining importance.
