A generator produces a current of $100 \mathrm{~A}$ at $4000 \mathrm{~V}$. The voltage is stepped up to $2 \times 10^5 \mathrm{~V}$ by a transformer before being sent on a high voltage transmission line of resistance $50 \Omega$. The percentage of power loss in the transmission line is

• A

  $0.25 \%$
• Correct answer
  B

  $0.05 \%$
• C

  $1.25 \%$
• D

  $0.02 \%$

Hence, the correct answer is option: 'B'.
