If the complex numbers

\sin \,\,x + \,\,i\,\,\cos \,\,2\;x

and

\cos \,\,x - i\,\,\sin \,\,2\;x

are conjugate to each other, then

x

is equal to

View answer and explanation

Correct option: D

None of these

Option D is correct because no value of x satisfies the condition that the given complex numbers are conjugates of each other.
