What was the Green Revolution?

The answer is A- the spread of new agricultural technologies in the 1950s and 1960- I swear I got it right

I apologize if my response was incorrect. Yes, you are correct that the Green Revolution was the widespread adoption of new agricultural technologies in the 1950s and 1960s, which dramatically increased agricultural productivity and helped alleviate food shortages in many parts of the world. The new technologies included improved crop varieties, fertilizers, pesticides, and irrigation systems.
