Correct Answer:
B. Fasting
The correct answer is Fasting. Fasting (Sawm) can be used as Kaffarah (expiation) for certain sins, such as breaking an oath or intentionally breaking a fast during Ramadan without a valid excuse. It serves as a means of atonement and seeking forgiveness from Allah.
- Zakat is obligatory charity given to the poor and needy, not typically used for expiation.
- Hajj is the annual pilgrimage to Mecca, a pillar of Islam, but not a form of Kaffarah.
- Therefore, 'None of these' is incorrect as Fasting is a valid option.
