HOLA!!!
______
HERE YOUR ANSWER IS
Lemme say what you should remember
we know
resistivity = resistance × area of cross section /l
where I = length
Resistance = resistivity × length/area of cross section
Resistance is inversely proportional to area of cross section
when means
* more resistance when wire is thin.
*less resistance when wire is thick.
Therefore thin wire has greater resistance.

Wire thickness does not depend upon resistivity.
Affect* not depend
No resistance depends on its length, on its area of cross section , on nature of material
