Best answer
Right option is (b) Shows default packages in R

The best I can explain: There are base packages (which come with R automatically), and contributed packages. The base packages are maintained by a select group of volunteers, called R Core. In addition to the base packages, there are over ten thousand additional contributed packages written by individuals all over the world.
