Correct answer: A
Concept: When two pie charts split the same whole (here, total body weight) into different sets of categories, each category's percentage share is already a fraction of that one common total. So any category's weight can be expressed as a percentage of any other category's weight using: (Category A % ÷ Category B %) × 100.
From the first pie chart, Skin makes up 1/10, i.e., 10% of total body weight.
From the second pie chart, Proteins make up 24% of total body weight.
Percentage of protein weight equivalent to skin weight = (Skin % ÷ Protein %) × 100 = (10 ÷ 24) × 100.
This simplifies to 1000/24 = 41.6666...%, which this question's convention states as 41.66% (to two decimal places).
Cross-check: 24% × 41.66% is approximately 10%, which matches the skin's charted share of 10%, confirming the calculation is consistent.
So the weight of skin is equivalent to 41.66% of the weight of proteins in the human body, matching this option.
