The correct answer is (a). In the “Ahsan Form” of talaq, the talaq is effective from the moment of pronouncement. This means that the marriage is immediately dissolved when the husband pronounces the talaq. The wife is then required to observe a waiting period (iddah) of three menstrual cycles or three months, whichever is shorter. After the iddah period has ended, the wife is free to remarry.
The other options are incorrect. Option (b) is incorrect because the talaq is not effective on the expiration of the iddah period. The iddah period is a waiting period that is required of a woman after the dissolution of her marriage. The purpose of the iddah period is to ensure that the woman is not pregnant with her former husband’s child. Option (c) is incorrect because the talaq is not effective on the third pronouncement. In the “Ahsan Form” of talaq, only one pronouncement is required to dissolve the marriage. Option (d) is incorrect because the talaq is not effective from the execution of the writing of talaq-nama. The talaq-nama is a document that is used to record the talaq. However, the talaq is not effective until the husband pronounces the talaq.
