A power transmission line feeds input power \( t 2300 \mathrm{V} \) to a step-down transformer with its primary windings having 4000 turns. The output power is delivered at \( 230 \mathrm{V} \) by the transformer. If the current in the primary of the transformer is \( 5 \mathrm{A} \) and its efficiency is \( 90 \%, \) the output current would be :

• A. 25 A
• B. 50 A
• C. 35 \mathrm{A} \)
• D. 45 A
