Answer:
Option D, both A and B
Explanation:
The potential difference is created across a battery (between its two terminal –one positive and the other one negative) when work is done to move a charge from one point to another. This potential difference is measured in volts. 1 volt is the potential difference between two points when one joule of potential energy is spent to move a charge of one coulomb from one point to the other.
Voltage drop across a circuit is the amount of electric current lost due to resistance/ impedance with in the cables of the circuit.
Hence, both potential difference and voltage drop occurs across the circuit,
Option D is correct.
A molecule is made of more than one atom of differing elements that can be simplified while an element cannot be simplified because it is only one atom of one type of element.
