Answer 1

Correct option is (a) save (x, file=”x.Rdata”)

Explanation: The function save() can be used to save one or more R objects to a specified file (in .RData or .rda type file formats). The function can be read back from the file using the function load(). Note that if you save your data with save(), it cannot be restored under a different name.
