Final answer:
The Karl Fisher analysis is used to determine the moisture content of a substance. Lyophilized allograft tissue is unlikely to have a residual moisture exceeding 8% based on the water content found in different body organs and tissues.
Step-by-step explanation:
The question is related to Karl Fischer analysis, which is a method used to determine the moisture content of a substance. In this case, the question is asking about the residual moisture of lyophilized allograft tissue. According to the information provided, the water content in different body organs and tissues can vary significantly. The highest water content is found in the brain, which is 85 percent.
Based on this information, it can be inferred that lyophilized allograft tissue, which is a type of tissue graft preserved through freeze-drying, would have a relatively low water content. Therefore, it is unlikely to have a residual moisture exceeding 8 percent, which is the highest water content found in the body.
Therefore, the correct answer to the question is option c. 8%.
