c. create a voltage
d. eliminate a voltage

B - increase in voltage

Explanation: in a step up transfer / transformation of voltage in transformers, the voltage on the primary coil is STEPPED UP thereby increasing the voltage of the secondary coil for easy transmission, because voltage is easily transmitted/ transferred over long distance with high voltage to minimize losses.
