The more baryons there are in the universe (a higher density of baryonic matter), the lower the ratio of deuterium to hydrogen is. therefore, if harry measures a higher ratio of deuterium to hydrogen than sally, harry infers:
a) the same density of baryons as sally.
b) a lower density of baryons than sally.
c) a higher density of baryons than sally.
