Yes, you look at temperature that is given in the problem. And this also helps to solidify the concept that equilibrium constants are temperature dependent. So at different temperatures, the equilibrium constants are different.

You would have to look at the given temperature in the problem as well as if the compounds are gases because the last column in the table has the Kc for gases.
