I am assuming River= Condos with a view and Noriver= Condos without a view and hence below four are correct options
140 Days to Sell is plausible value for condos without a view.
120 Days to Sell is a plausible value for BOTH condos with and without a view.
140 Days to Sell is plausible value for condos with a view.
80 Days to Sell is a plausible value for either kind of a condo. (those with a view and without)
