The correct answer is Being Obedient to the will of God.
Explanation:
The basic concept of Islam is to accept the belief that God is one and there is no other God than ALLAH, and to accept the teachings and orders of God given to people through messengers. So it means a true Muslim must inherit the element of obedience in his own self. This is the basic concept of the Muslim Belief System. So Being Obedient to the will of God is the correct answer. Being submissive to ALLAH and do whatever the teachings of the religion are, are the basic concept of Islam. A true Muslim is an obedient man of the God.
