The Salah is one of the five pillars of Islam that obliges Muslims to pray five times a day. The act of worship is not only physical, but also mental and spiritual. The Muslim starts by laying down a mat or carpet and bows while praying. The answer thus is B. salah
Praying five times a day toward Mecca is required to fulfill the second pillar of Islam that is salat. Muslims are required to pray at sunset, evening, dawn, noon and of course in the afternoon. The announcement that signals prayer time is done atop the mosque.
