A
That's an easy one, because the heat can increase resistance, the material composing the body is what a resistor is all about and the length of those parts can't help but determine the resistance value.
Bodies surrounding the body of the object can effect the electrical resistance of a substance, but without touching the item in question they aren't even part of the circuit so that means they can pretty much be ignored.

A. Bodies directly surrounding the body, because the body is most likely the path of least resistance and the outer body therefore does not effect it's resistivity
and temp, mat'l and length affect resistance

A.
B- temps always effect the conductivity of electricity
C-that's an easy one, obviously metals are more conductive than nonmetals and it would be the same thing here.
D-the longer and more surface area a surface has the more electricity will resist movement. Ever heard of signals losing strength over long distances? This is why

Pennfoster answer is A. Just did my test and got it correct
