Concept:A valid Islamic marriage requires certain essential conditions, including the presence of witnesses.
Explanation:The presence of two adult male witnesses is a key condition for a legal marriage in Islam.
These witnesses must be sane, adult, and trustworthy Muslims.
A marriage certificate is only a record, not a core condition.
Officiating Imams and Alfas may conduct the ceremony, but their presence is not mandatory for the marriage to be legal.
Rings are cultural symbols, not legal requirements.
Therefore, the correct legal condition is the presence of two adult male witnesses.
Answer:Two Adult male witnesses (Option C).
