Detailed Solution :

The correct statement among the following is: Voltmeter is connected in parallel because it measures the potential difference across the two points of a circuit, and if it is connected in series with the load, it will change the voltage being measured.
While it is true that voltmeters generally have high resistance, this is not the main reason why they are connected in parallel. The main reason is that a voltmeter needs to measure the potential difference between two points in a circuit, and connecting it in series with the load will cause a voltage drop across the voltmeter, which will change the voltage being measured.
By connecting a voltmeter in parallel, it measures the voltage across its terminals, and does not change the voltage being measured. Since the resistance of a voltmeter is generally high, it draws very little current from the circuit, which does not affect the voltage being measured.
Therefore, the correct statement is that voltmeter is connected in parallel because it measures the potential difference across the two points of a circuit, and if it is connected in series with the load, it will change the voltage being measured.

Hence, the correct option is C
