For the complex number z = StartFraction 5 StartRoot 3 EndRoot Over 4 EndFraction minus StartFraction 5 Over 4 EndFraction i ,what is the polar form?

correct one - A.) z = five-halves (cosine (StartFraction pi Over 6 EndFraction) + I sine (StartFraction pi Over 6 EndFraction)

B.) z = five-fourths (cosine (StartFraction pi Over 6 EndFraction) + I sine (StartFraction pi Over 6 EndFraction)

- C.) z = five-halves (cosine (StartFraction 11 pi Over 6 EndFraction) + I sine (StartFraction 11 pi Over 6 EndFraction)

D.) z = five-fourths (cosine (StartFraction 11 pi Over 6 EndFraction) + I sine (StartFraction 11 pi Over 6 EndFraction)
