Final answer:

It is essential to check the context or additional information provided with the question to ensure that the length corresponds to the correct Clear Lake.
For the purposes of this exercise, we are not confident in the correctness of any part of the answer, as the provided options do not include the actual length of the shoreline of Clear Lake, California. In an actual scenario, the student should verify the Clear Lake in question and refer to reliable geographic resources for the accurate measurement of the lake's shoreline.
