B. 60

Explanation:

At age 20, Spartan males became full-time soldiers, and remained on active duty until age 60. The Spartans’ constant military drilling and discipline made them skilled at the ancient Greek style of fighting in a phalanx formation. In the phalanx, the army worked as a unit in a close, deep formation, and made coordinated mass maneuvers.
