Are the unit vectors i,j and k directions defined by a left-handed coordinate system?

A friend asked me this question today. It kinda threw me for a loop. The cartesian coordinates system is a left handed coordinate system right, so therefroe they are defined by a left handed coordinate syste correct?

The Cartesian coordinate system is a right-handed system.

The Cartesian coordinate system is a right-handed system.
Not necessarily. That is an extremely common, but not universal, convention.

Or he/she is a geologist, or a radar technician, or a GPS specialist, or someone else who (danged annoyingly!) works with north-east-up coordinates.
