\sf - 6i

The modulus r, of a pure imaginary number bi, b<0, equals |b| and its argument θ equals \frac{3\pi}{2}

\sf \: r = 6 \\  \sf \theta =  \frac{3\pi}{2}

Substitute the given values into the formula r(cos(θ)+i×sin(θ))

\sf6( \cos( \frac{3\pi}{2} )  + i \times  \sin( \frac{3\pi}{2} ) )

Since, The value of 3π/2 is 270°.. Put it in the equation

\boxed{ \tt6( \cos270  + i \times  \sin270) }

<em>Thus, Option B is the correct choice!!~</em>
