Answer

At an early age.

Answer

At an early age.

Answer

The first one is correct, only you don't need all the capitalization:
Children learn a second language at an early age.

Answer

The preposition "at" is used to refer to a point in time:   at 5 o'clock; at Christmas; at an early age.

The specific point in time does not have to refer only to hours, minutes or seconds.
It can refer to and be used to refer to a point in time or a period of time, such as the years when someone is young or old.
For example:  They shouldn't be playing football at their advanced age.

So, as the others have pointed out: Children learn a second language at an early age... [correct]
