There is all ready total resistance is 3 kilo-ohm.
If resistance less then least effect on source voltage.
So I think 330 ohm is small resistance so answer is this one.

Least effect means voltage will lesson than the previous voltage or greater than the previous voltage.

How possible total resistance in series is 3 ohm? while every resistance has a value of 1 Kohm.

If R is max then current I will be less thus least effect on the circuit.

Can anybody explain difference between least effect and most effect.

1*1/1+1 = 2/2 how can possible & same R1*R2=1000*3 possible.

Please, someone explain me briefly. I don't understand still.

Output voltage = r1.r2/r1+r2 = 1.1/1+1 = 2/2 = 1 m ohms

1K because all resisters are same value so ans is 'C'

Use the rule of voltmeter impact on measured circuit.
