An open circuit in a voltage divider means that there is a break in the circuit, preventing current from flowing. In a voltage divider composition, resistors are arranged to divide the voltage proportionally. When an open circuit occurs, no current passes through any of the resistors, which leads to zero voltage drop across them. This is because Ohm's Law states that voltage (V) is equal to current (I) multiplied by resistance (R) (V = IR). If the current (I) is zero due to the open circuit, then the voltage drop across each resistor is also zero, resulting in the voltage across the resistors being effectively zero.

This reasoning directly supports the choice that says the voltage across the resistors will be zero. The other options describe scenarios that are not applicable to an open circuit in this context, such as increased current flow or voltage distribution among resistors.
