I think c too. The size of the gap is larger than the wavelength so diffraction happens only at the edges. I found all the papers here.

Think ratios and ignore the bus. Just take the passengers into accoount. For B the cog is 1/5 of the way from the bottom to top passengers but for A the cog is at the level of the bottom passengers.

I dont think you really need to worry about the ratio. Just because there is someone on the top the cog will be higher up
