Concept:Zakat is an obligatory charity, and Qur'an 9:60 clearly mentions the categories of people who may receive it.
Explanation:In Surah At-Tawbah, verse 9:60, Allah specifies eight eligible groups for Zakat.
These include the poor, the needy, Zakat collectors, those whose hearts are to be reconciled, slaves, debtors, those in Allah's cause, and the wayfarer.
The "wayfarer" means a needy traveller who is stranded during a journey and requires help, even if he is not poor in his own land.
The other options, such as the caller to prayer (Mu'adhdhin), the blind, or the Qur'an commentator (Mufassir), are not among the eight categories mentioned in this verse.
Answer:Hence, the correct answer is C. wayfarer.
