Concept:The final act that completes the Muslim prayer is called Taslim.
Explanation:During prayer, a Muslim ends by turning the head to the right and then to the left.
While doing this, the person recites the greeting:
As-salamu alaikum wa-rahmatu-llah.
This concluding portion is known as Taslim.
It marks the end of the prayer, so a complete prayer ends with Taslim.
The other options — Tashahhud, Basmallah, and Tahlil — are recited at different points and do not close the prayer.
Answer:B. Taslim
