How to approach it

Predict from the governing principle before looking for a matching option. Then reject alternatives by checking direction, units, limiting behaviour or the physical meaning of each statement.

  1. 1

    The correct choice is B: red supergiant → supernova → neutron star or black hole

  2. 2

    A is the route for a star of about the Sun's mass, and is the answer of a candidate who has learned one life cycle rather than two.
