Answer:

  • Option B

Explanation:

Given:

  • 4 - 3i

Conjugate of the given number is:

  • 4 + 3i

Divide the given number by its conjugate:

  • (4 - 3i) / (4 + 3i) =
  • (4 - 3i)(4 - 3i) / (4 + 3i)(4 - 3i) =
  • (16 + 9i² - 24i) / (16 - 9i²) =
  • (16 - 9 - 24i) / (16 + 9) =
  • (7 - 24i) / 25 =
  • 7/25 - 24i/25

Correct choice is B
