{z_1},{z_2},{z_3}, \ldots ,{z_n}

are

n

nth roots of unity, then for

k = 1,2, \ldots ,n

View answer and explanation

Correct option: D

\left| {{z_k}} \right| = \left| {{z_{k + 1}}} \right|

Option D (

\left| {{z_k}} \right| = \left| {{z_{k + 1}}} \right|

) is correct because all nth roots of unity lie on the unit circle, hence their magnitudes are equal to 1.
