ANSWER::
If the value of commodity A is less than 30 then 95.4% of people are willing to pay for it, for the commodity B this value is 37.3%, for the commodity C this value is 46.2%, and for the commodity D this value is only 5.7%. That means commodity A has the highest demand if its value is less than 30.
If the value of commodity A is between 31 and 60 then 1.5% of people are willing to pay for it, for the commodity B this value is 47.8%, for the commodity C this value is 36.4%, and for the commodity D this value is 25.9%. That means commodity B has the highest demand if its value is between 31 and 60.
If the value of commodity A is between 60 and 90 then 1.5% of people are willing to pay for it, for the commodity B this value is 11.7%, for the commodity C this value is 10.8%, and for the commodity D this value is 33.2%. That means commodity D has the highest demand if its value is between 60 and 90.
If the value of commodity A is 90 or more than 90 then 1.5% of people are willing to pay for it, for the commodity B this value is 3.2%, for the commodity C this value is 6.6%, and for the commodity D this value is 35.1%. That means commodity D has the highest demand if its value is more than 90.
