Many exoplanets have been discovered by the transit method, wherein one monitors a dip in the intensity of the parent star as the exoplanet moves in front of it. The exoplanet has a radius `R` and the parent star has radius `100R`. If `I_(0)` is the intensity observed on earth due to the parent star, then as the exoplanet transits,A. The minimum observed intensity of the parent star is `0.9I_(0)`B. The minimum observed intensity of the parent star is `0.99I_(0)`C. The minimum observed intensity of the parent star is `0.999 I_(0)`D. The minimum observed intensity of the parent star is `0.9999 I_(0)`
