Answer» The correct option is (b) colnames() The explanation: colnames() is the FUNCTION to set column names for a matrix. rownames() is the function to set ROW names for a matrix. But we can’t use both at a time. Column names and row names can be set separately using the colnames() and rownames() functions.
