Let

z

be a complex number such that the imaginary part of

z

is non-zero and

a=z^2+z+1

is real. Then,

a

cannot take the value

View answer and explanation

Correct option: D

\frac{3}{4}

Option D (

\frac{3}{4}

) is correct because if

a = \frac{3}{4}

, then z would be real, contradicting the condition that the imaginary part of z is non-zero.
