Given below are two statements : One is labelled as Assertion A and the other is labelled as Reason R. Assertion A; For measuring the potential difference across a resistance of $600 \Omega$, the voltmeter with resistance $1000 \Omega$ will be preferred over voltmeter with resistance $4000 \Omega$. Reason R: Voltmeter with higher resistance will draw smaller current than voltmeter with lower resistance. In the light of the above statements, choose the most appropriate answer from the options given below.
