Option 1: A decline in global malnutrition rates.
Incorrect -> The passage clearly shows rising malnutrition, not a decline.
Option 2: A reduction in food insecurity through economic growth.
Incorrect -> No link to economic growth is mentioned; the impact described is negative.
Option 3: An increase of 10 million people towards extreme poverty.
Correct -> The passage explicitly states that the World Bank estimated a 1% rise in global food prices could push 10 million people into extreme poverty.
Option 4: No significant impact on food security.
Incorrect -> The passage highlights severe impacts on food security and poverty.
Hence, Option 3 is the correct answer.
