obesity rates for children aged 2 - 5 doubled.
obesity rates for all age groups increased.
obesity rates for individuals aged 12 - 19 increased the most.
obesity rates for children aged 6 - 11 increased the least.
more than 15% of all children aged 6 and over were obese in 2008.

Explanation:

1. For "Obesity rates for children aged 2–5 doubled": In 1971 - 1974, the rate for 2 - 5 year - olds was around 5%, and later it reached around 10%, so it doubled.
2. For "Obesity rates for all age groups increased": The lines for 2 - 5, 6 - 11, and 12 - 19 year - olds all show an upward trend from the start (1971 - 1974) to the end (2007 - 2008) of the graph.
3. For "More than 15% of all children aged 6 and over were obese in 2008": In 2007 - 2008, the obesity rate for 6 - 11 year - olds and 12 - 19 year - olds is above 15%, so more than 15% of children aged 6 and over were obese.

(Note: The option "Obesity rates for individuals aged 12–19 increased the most" is incorrect as the rate for 6 - 11 year - olds also had a significant increase and at some points was similar. The option "Obesity rates for children aged 6–11 increased the least" is also incorrect as the increase for 2 - 5 year - olds was relatively smaller in magnitude compared to 6 - 11 year - olds in some periods.)

Answer:

• Obesity rates for children aged 2–5 doubled. (Initially, the rate for 2 - 5 year - olds was around 5% and later around 10%, so it doubled)
• Obesity rates for all age groups increased. (All three lines (2 - 5, 6 - 11, 12 - 19 year - olds) show an upward trend from 1971 - 1974 to 2007 - 2008)
• More than 15% of all children aged 6 and over were obese in 2008. (In 2008, the rates for 6 - 11 and 12 - 19 year - olds are above 15%)
