B) rise by 3.2% if incomes rise by 10%
C) fall by 3.2% if price rises by 10%
D) rise by 3.2% if the price rises by 10%

YED is the % change in quantity demanded divided by the % change in income, so it is the gradient of the demand curve when the axes are income against quantity. Negative YED means the potatoes are an inferior good. You could just calculate the YED for each one and see which one is correct,

For B , well that's not it, so do the same for the other options and find the one that has a YED of -0.32.
