None of the above.

Detailed explanation-1: -The molecules in the pastry and filling have the same average kinetic energy as the pie comes out of the oven. Despite the temperatures being equal, your tongue is still more likely to get burned by the filling than the crust, though. There are 2 principles behind this: thermal conductivity and specific heat capacity.
Detailed explanation-2: -Serving pie hot from the oven isn’t just a bad idea aesthetically-all that hot sugar is also dangerous. Allow your pie to cool for about an hour. The filling will set, and it will be cool enough to eat, yet still a little warm.
Detailed explanation-3: -Pie filling is a better conductor than the crust, and the crust is already closer to an insulator, so at the same temperature the filling would retain would more heat than the crust, making it hotter.
Detailed explanation-4: -Add a Layer Sprinkle dried breadcrumbs or crushed cornflakes, or other types of cereal, on the bottom crust before filling and baking in the oven. This will prevent the filling from turning the crust soggy.
