Option (b) is the correct answer because option of puberty is available to the wife only. Option of puberty is a right that is given to a Muslim woman who has not reached puberty at the time of her marriage. This right allows her to annul her marriage if she does not want to continue with it. The option of puberty can be exercised by the woman herself or by her guardian on her behalf.
The option of puberty is a safeguard for young Muslim women who are married off at a young age. It gives them the opportunity to terminate their marriage if they do not want to continue with it. This is important because it allows young women to have a say in their own lives and to make their own choices about their future.
