Answer 1

Hint: When Alexander tried to march across river Ganges, his army, worn out by the hard-fought battle with Porus mutinied against the move. Succumbing to their mutiny, Alexander decided to send back a portion of his squad under the command of his naval commander.

Complete Answer: Alexander sent back home half of his army under the command of Admiral Nearchus through the Persian Gulf. He carried on with the other half of his army through the Gedrosian Desert in 325 BCE, almost a full year after his troops had mutinied.
Nearchus, along with Ptolemy was one of Alexander's mentors. He was exiled by Philip as a result of the Pixodarus affair, and recalled on the ascension of Alexander. Later, he was appointed as the admiral of the naval fleet raised by Alexander at Hydaspes. He is famous for his historic voyage from Indus river to the Persian Gulf
Ptolemy was one of Alexander’s companions and his historian during his conquests. He himself wrote an eyewitness history of the great conquests by Alexander. Menander was a general serving under Alexander the Great who held command of a body of mercenaries. Porus was an ancient Indian king who fought against Alexander and lost at the battle of Hydaspes.
So the correct answer is an option (B): Nearchos. Alexander sent back half his army under Admiral Nearchos.

Note: Alexander the Great had a legendary naval fleet which were commanded by the likes of Nearchus. who is known for his celebrated expeditionary voyage starting from the Indus River, through the Persian Gulf and ending at the mouth of the Tigris River following the Indian campaign of Alexander the Great.
