Two circularly shaped linear polarisers are placed coaxially. The transmission axis of the first polarizer is at `30^(@)` from the vertical while the second one is at `60^(@)`, both in the clockwise sense. If an unpolarised beam of light of intensity `I = 20 W//m^(2)` is incident on this pair of polarisers, then the intensities `I_(1)` and `I_(2)` transmitted by the first and the second polarisers, respectively, will be close to

Options

A. `I_(1) = 10.0 W//m^(2)" and "I_(2) = 7.5 W//m^(2)`
B. `I_(1) = 20.0 W//m^(2)" and "I_(2) = 15 W//m^(2)`
C. `I_(1) = 10.0 W//m^(2)" and "I_(2) = 8.6 W//m^(2)`
D. `I_(1) = 15.0 W//m^(2)" and "I_(2) = 0.0 W//m^(2)`
