Option b is the correct answer Alexander the Great was a Greek king and military leader who is best known for his conquests of the Persian Empire and his campaigns in Asia and Africa. The Various reason for Alexander success in India are as follows: Alexander often faced armies that were divided and disorganized, which made it easier for him to defeat them. India was divided into small kingdom, there was no central power in India at that time. The Macedonian army was well-equipped with advanced weapons and armor, which gave them an advantage in battle. Whereas Indian army was having traditional weaponry at that time. Alexander was supported by many traitorous Indian Rulers. King Ambhi was the ruler of taxila during Alexanders Invasion. Ambhi had bitter relations with his neighbor king Porus (called as Parvateshwar or Purushottam). It is said that he helped Alexander to rage a battle against the mighty Porus. As historian Robin Waterfield notes, "Alexander seems to have concerned himself little with administration, beyond the bare minimum necessary for an ongoing conqueror to secure his rear." Alexander the Great ignored the difficult process of consolidating his conquered territories. Thus, it seems that he was not a good administrator, but was a good conqueror. Hence statement 4 is incorrect.
