  When we say 'survival of the fittest', does it mean that (a) those which are fit only survive                                        (b) those that survive are called fit? Comment,                         

Answer:

                  In the struggle for existence, the individuals which have more favourable variations will enjoy a competitive advantage over others which have less favourable or unfavorable variations. They are considered fit and thus, will survive and reproduce. Such individuals produce more progeny (with more fit individuals) than others who are less adapted in that environment.
