A mixture of polarised and unpolarised light is incident on a polariser. As the polariser is rotated through\[360{}^\circ \], it is found that the minimum and the maximum of the transmitted intensity is in the ratio 1: q. The ratio of intensities of polarized to unpolarised light in the incident beam is

A) \[\frac{1}{2}(q-1):1\]

B) \[1:\frac{1}{2}(q-1)\]

C) \[\frac{1}{2}q:1\]

D) \[1:\frac{1}{2}q\]
