Explanation

Maaz Bin Jabal is historically associated with being appointed to govern Yemen by the Prophet. Hazrat Abu Musa Ashri R.A was sent on other missions and his role in governing North Yemen specifically is not the primary historical attribution. Hazrat Amer Ibn Alas's specific appointment as governor of North Yemen by the Prophet is less commonly cited than Maaz Bin Jabal's. Therefore, option A is the most likely correct answer based on standard Islamic history texts.
