Which of the following expressions will read the space-delimited file "info.dat"?

• Assume that all the necessary packages are already loaded.
• Assume the working directory has the following structure.

read_delim(here::here("data", "info.dat"), delim = " ")read_delim(here::here("info.dat"), delim = " ")read_tsv(here::here("data", "info.dat"), delim = " ")read.table(here::here("data", "info.dat"), header = TRUE, sep= " ")read.table(here::here("data", "info.dat"), header = TRUE)

• CORRECT: read_delim() is the correct tidyverse function. Here, we specify the space character as the delimiter.
• INCORRECT: The file path is wrong.
• INCORRECT: The function read_tsv() is for reading tab-delimited files.
• CORRECT: read.table() is the correct Base R function. Here, we specify the space character as the delimiter.
