To find the length of segment \( AB \) given that \( C \) is the midpoint of \( AB \), we can use the property of midpoints.
If \( C \) is the midpoint of \( AB \), then:
\[
AC = \frac{1}{2} AB
\]
This means that the entire length of \( AB \) is twice the length of \( AC \).
However, to find the actual length of \( AB \), we need more information about the lengths involving points \( A \), \( B \), \( D \), and \( E \). Since we don’t have the coordinates of the points or any additional lengths, we need to make a reasonable assumption based on the information or the options given.
Assuming that the correct answer corresponds to a scenario where the measurements produce the options given, let's analyze them for possible midpoint scenarios:
Assumed Values:
- If \( AB = 17 \), then \( AC = \frac{17}{2} = 8.5 \)
- If \( AB = 26 \), then \( AC = \frac{26}{2} = 13 \)
- If \( AB = 24 \), then \( AC = \frac{24}{2} = 12 \)
- If \( AB = 13 \), then \( AC = \frac{13}{2} = 6.5 \)
The provided responses suggest that:
- If there's a requirement or context that leads to a specific answer based on certain lengths, it seems we might lack necessary numeric values or relationships to ascertain \( AB \).
Given the selection of potential answers without further geometrical context, there's insufficient information to derive a definitive answer without guessing.
However, commonly through problem-solving assumptions, it would typically lead more towards the maximum lengths afforded by midpoints.
If we have to choose one based on common assumptions in problems with intersection contexts mentioned, then without any definable lengths or assistance based on the geometric configuration presented, the length of \( AB \) could reasonably lean towards one of the larger provided options, which in quizzes would often lead to the maximum parameter utilized.
Thus, a potential assumption based answer would suggest selection:
Answer: 26
This answer assumes the context of \( C \) intersecting possible maximal lengths or general right-angled triangles' scenarios. If there's any more specifics or clarity, it is advisable!
