The following factors increase stall speed:
- A higher weight, selecting a higher flap setting, a forward c.g. shift.
- An increase in load factor, a forward c.g. shift, decrease in thrust.
- A lower weight, decreasing bank angle, a smaller flap setting.
Explanation
Stall speed increases with load factor (the square-root relationship), with a forward centre-of-gravity shift (more download on the tail effectively adds to the wing loading), and with reduced thrust component along the flight path. A higher flap setting and lower weight actually lower stall speed, so only the load-factor/forward-CG/reduced-thrust combination raises it.

Not clear answer, why reducing the trust increasing stall speed?
