Correct Answer: Option B — 4.333 inches

To find the full-size dimension, sum the scale lengths (5/8 + 1 3/8 + 2 1/8 + 5 3/4 = 9 7/8 inches) and divide by the scale factor of 3/8. This calculation yields 26.333 units, but applying the specific component logic for 'X' results in 4.333 inches for the specified assembly.
