Final Answer :
C
Explanation :
Studies have shown that about 40% of the difference among people's happiness ratings is heritable, meaning that it can be attributed to genetic factors. While environmental factors such as life circumstances and individual choices still play a significant role in determining happiness, genetics also plays a significant role. This finding reinforces the idea that there is no single "recipe" for happiness and that it is a complex interaction of various factors.
