The pH scale is logarithmic, meaning each whole pH value below 7 is 10 times more acidic than the next higher value. Therefore, a solution with a pH of 6 has 10^2 = 100 times more H+ ions than a solution with a pH of 8. None of the provided options accurately describe this relationship, but option B is the only one that suggests there are more H+ ions at pH 6, which is correct in a comparative sense, despite the numerical inaccuracy.
