To convert the length of the Boston Marathon course from yards to feet, we need to know that there are 3 feet in a yard.
Given the length of the course is 46,145 yards, we can calculate the length in feet as follows:
\[
46,145 \text{ yards} \times 3 \text{ feet/yard} = 138,435 \text{ feet}
\]
Now, to find the best estimate from the given options, we can round 138,435 to a more manageable form:
\[
138,435 \approx 1.38 \times 10^5
\]
Thus, the best estimate of the length of the Boston Marathon course in feet from the provided options is:
\[
\boxed{1.38 \times 10^5}
\]
