744 speed logic

The 744 FCTM states that speed should be manually controlled when on approach and this requires use of speed intervene.
The question I have is if you are positioning on base leg in VNAV PTH and select Flap 1 and do not open the MCP speed window then what speed does the speed bug now go to? (assuming no limiting waypoint or ALT speed constraint):

A. F1 reference mark on the speed tape
B. Top of the amber band on the speed tape
C. 5 kts (or other margin) above the top of the amber band
D: Other. If so could you please explain.

Many thanks
