Answer:
The Hadean eon represents the time interval between 4.6 billion to 4 billion years back. It is marked by the initial formation of the earth , right from the time of gathering and accumulation of interstellar dust particles and gases, and there was frequent collision between the planetesimals of relatively larger in size. The core and the crust formed and started to become stable and also gradually led to the formation and expansion of the ocean and the earth's atmosphere.
This is how the earth gradually started to form and develop and took the shape during the time interval between 4.6 billion to 4.2 billion years old, and where the oldest rocks found on earth is dated from about 4.2 billion years in the past.

Explanation
The image shows a pie chart showing the population percentages in Florida in 2013 by age. In this graph there are 5 main groups: Dark blue color that represents the population of 19 years or less, which corresponds to 23.5%; yellow color represents the population from 20 to 39 years old, which corresponds to 25.1%; green color represents the population from 40 to 59 years old, which corresponds to 27.5%; The red color represents the population aged 60 to 79, which corresponds to 18.8%. According to this information, it can be concluded that about 75% of the population is 59 years of age or younger.
This can be verified by adding the percentages of each population 23.5% (19 years or less) plus 25.1% (twenty to thirty-nine years) plus 27.5% (forty to fifty-nine years) add up to 76.1 %.
So the correct answer is D. 59 years and younger.
