The line of position determined from a sight with an observed altitude (Ho) of 88°45.0' should be __________.

Correct Answer: Option B — plotted as an arc around the GP of the body

According to Bowditch, when a celestial body's observed altitude exceeds 87 degrees, the intercept method fails because the radius of the circle of equal altitude is too small. It must be plotted directly as a circular arc centered on the body's GP.
