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 homogeneous mixture is not considered a pure substance because it can be separated through mechanical and thermal processes. A pure substance, however, cannot be separated.<span>

Life is a special thing. You have your time and when it is decided that you will pass on then you go to a special place un-known to our world.
