    The answer is d. since\[\Delta V = V_o \beta \Delta T\], both the initial volume and the change in volume are involved. A larger bulb will cause a larger change in volume, so if the tubes are the same, a larger bulb will have a bigger change in the level. Also, all other things being equal, a smaller diameter stem would have a larger change for the same change in temperature. The bulb is Vo while the tube absorbs the delta V.
