What is the correct output for TO_CHAR({today}, 'Day')?

The correct output for the function TO_CHAR({today}, 'Day') is indeed the day of the week corresponding to the current date formatted as a string. When you use TO_CHAR with the 'Day' format, it generates the full name of the day of the week for the provided date, which in this case is represented by {today}.

If today were a Friday, TO_CHAR would output 'Friday', displaying the name of the day. This function is commonly used in SQL and various database systems, including NetSuite, to convert date or time values into a specified string format.

Other options don't accurately represent the function's behavior: 'Today' suggests a direct reference to the date itself, 'Day' simply states the formatting instruction, and 'Current Date' is a vague description that does not relate to the output of the TO_CHAR function. Thus, the choice that indicates 'Friday' is correct when {today} falls on that day.
