Best answer
Correct option is (c) ?

The best explanation: The help() function and ? help operator in R provides access to the documentation pages for R functions, data sets, and other objects, both for packages in the standard R distribution and for contributed packages. At any time, you can type ? (keyword) to open the help window for a particular subject.
