Jones oxidation of ethanol yields which product?

The main concept is that Jones oxidation uses a strong Cr(VI) oxidizing reagent in acidic conditions to convert primary alcohols all the way to carboxylic acids. Ethanol is a primary alcohol, so under Jones conditions it is oxidized first to the aldehyde (ethanal) and then further to the carboxylic acid (ethanoic acid, i.e., acetic acid). Since Jones oxidation pushes primary alcohols to the carboxylic acid, the product is acetic acid. The other possibilities would correspond to stopping at the aldehyde or forming esters, which don’t arise from this strong oxidation of a primary alcohol.
