A boy throws an unbiased die. Whenever he gets 1 on the die he has a further chance to throw it once again immediately. The probability that the boy gets a score of 7 in this process is
- A \(\frac{1}{5}\left(1-\frac{1}{6^5}\right)\)
- B \(\frac{1}{30}\left(1-\frac{1}{6^4}\right)\)
- C \(\frac{1}{30}\left(1-\frac{1}{6^5}\right)\)
- D \(\frac{1}{5}\left(1-\frac{1}{6^4}\right)\)
