Correct answer: D
In a pie chart, all the listed shares add up to 100% of the whole. So, to find the share of the whole that belongs to neither of two named categories, add those two categories' shares together and subtract the sum from 100%.
From the chart, the Bones share is 1/5, i.e., 20% of body weight.
From the chart, the Skin share is 1/10, i.e., 10% of body weight.
Add the two shares: 20% + 10% = 30%.
Subtract this combined share from the whole: 100% minus 30% = 70%.
Independently, the two remaining categories are Muscles (3/10 = 30%) and Hormones, enzymes and other proteins (2/5 = 40%). Adding these two shares directly gives 30% + 40% = 70%, the same value obtained above, confirming the result.
So, 70% of the human body is made of neither bones nor skin.
