Can 2-propanol give iodoform test?

No tertiary alcohols give the triiodomethane (iodoform) reaction. 1-propanol does not give a positive iodoform test. iodoform is a yellow solid and can be observed in the test while chloroform is a colourless liquid and cannot be noticed.

Most likely a is the answer - because  you generate   38 atp's but also consume an atp.   each atp gives approx. less than 4 kcal so probably a is the closest answer.
