In context of outer space, the term 'Lagrange Point' or 'Lagrangian Point' has been in news recently. Which of the following correctly describes the term?

A Lagrange point is a location in space where the combined gravitational forces of two large bodies equal the centrifugal force felt by a much smaller third body thereby creating a point of equilibrium where the smaller body can maintain its position relative to the two large bodies.

It is a point in the outer space which is neither too hot, nor too cold to support liquid water - thought to be a key ingredient for life.

Lagrangian point in space is created by a dying star where matter has been squeezed into a tiny space and the gravity pull is so much that even light cannot get out of such points.

None of the above is correct in this context

Explanation:

First option is correct. The Lagrange points mark positions where the combined gravitational pull of the two large masses provides precisely the centripetal force required to orbit with them. There are five such points, labelled L1 to L5, all in the orbital plane of the two large bodies.
