    Option C is the correct answer.

    Explanation:

    We know that in series connection current in all the resistors are same.

    Effective resistance is sum of individual resistances.

    Here three of 3 ohms, 5 ohms, and 22 ohms are connected in series in a 28-volt circuit

    Effective resistance = 3 + 5 + 22 = 30 ohms

    Voltage = 28 V

    We know

    Voltage = Current x Resistance

    V = IR

    28 = 30 x I

    I = 0.93 A

    Current in each resistor is 0.93 A

    Option C is the correct answer.
