Not quite. The answer is B: A guard complying with R312, with the plane of the glass more than 18 in from the guard.
The R308.4.7 exception applies where the glazing is protected by a guard complying with R312 and the plane of the glass is more than 18 in (457 millimeters) from the guard. A rail 24 in high does not match any exception; the rail exception in R308.4.6 uses a rail 34 to 38 in high resisting 50 plf. The trigger is the bottom edge below 36 in, so a low top edge does not exempt glazing. The 9 square feet pane size is a window condition under R308.4.3.
