C
increasing the temperature of almost any substance decreases its conductivity, thereby increasing resistance
a. is wrong because decreasing the length decreases resistance in almost all conductive materials.
b. the amount of voltage applied to the circuit does not change the resistance potential of the conductor, in fact the voltage is measured by the resistance, not vice versa.
c. correct answer
d. the area of the conductor will NOT necessarily increase resistance as the actual distance traveled may be the same.

Resistance R of a conductor =resistivity * length / area
Resistance does not depend on voltage applied
Resistance is directly proportional to length
Resistance increases with increase in length
Resistance is inversely proportional to area
Resistance decreases with increase in area
Resistance of conductor increases with rise in temperature
c is correct answer

check the question
see if this helps v=i times r
volts = current x resistance
