Answer:

The correct answer is Option 3.

Explanation:

Equivalent emf in the circuit,

V=E_{1} -E_{2}

   = 120-10

   = 110V

Equivalent resistance in the circuit,

R=R_{1} +R_{2}

   = 10+1

   = 11Ω

Current in the circuit,

I=\frac{V}{R}

  = 110/11

  = 10A

The terminal voltage of the battery =E_{2}- IR_{2}

                                                           = 10-10×1

                                                           = 0V

So, the terminal voltage of the battery is equal to zero volts.

Hence, option 3 is correct.
