Which is the correct formula of current flowing through one of the transformers having unequal ratios?

A. I<sub>2</sub>= E<sub>2</sub>Z<sub>1</sub>-(E<sub>1</sub>-E<sub>2</sub>) Z<sub>L</sub> / (Z<sub>1</sub>Z<sub>2</sub> + ZL(Z<sub>1</sub>+Z<sub>2</sub>))
B. I<sub>1</sub>= E<sub>2</sub>Z<sub>1</sub>+(E<sub>1</sub>+E<sub>2</sub>) Z<sub>L</sub> / (Z<sub>1</sub>Z<sub>2</sub> + ZL(Z<sub>1</sub>+Z<sub>2</sub>))
C. I<sub>1</sub>= E<sub>2</sub>Z<sub>1</sub>-(E<sub>1</sub>-E<sub>2</sub>) Z<sub>L</sub> / (Z<sub>1</sub>Z<sub>2</sub> ZL(Z<sub>1</sub>-Z<sub>2</sub>))
D. I<sub>2</sub>= E<sub>2</sub>Z<sub>1</sub>+(E<sub>1</sub>-E<sub>2</sub>) Z<sub>L</sub> / (Z<sub>1</sub>Z<sub>2</sub> + ZL(Z<sub>1</sub>+Z<sub>2</sub>))
Answer» B. I<sub>1</sub>= E<sub>2</sub>Z<sub>1</sub>+(E<sub>1</sub>+E<sub>2</sub>) Z<sub>L</sub> / (Z<sub>1</sub>Z<sub>2</sub> + ZL(Z<sub>1</sub>+Z<sub>2</sub>))
