The correct answer is A. split.

The split function is used to split a character vector into a vector of character vectors by splitting on a specified character or regular expression. The strsplit function is used to split a character vector into a vector of character vectors by splitting on a specified character or regular expression, but it also allows for more complex splitting patterns. The autsplit function is not a built-in function in R.

Here is an example of how to use the split function to split a name into first and last name:

“`
names <- c(“John Doe”, “Jane Doe”, “John Smith”)
split(names, names)

[[1]]

[1] “John” “Doe”

[[2]]

[1] “Jane” “Doe”

[[3]]

[1] “John” “Smith”

“`

Here is an example of how to use the strsplit function to split a name into first and last name:

“`
names <- c(“John Doe”, “Jane Doe”, “John Smith”)
strsplit(names, “\s+”)

[[1]]

[1] “John” “Doe”

[[2]]

[1] “Jane” “Doe”

[[3]]

[1] “John” “Smith”

“`
