A. split: The split function is used to split a string into a list of substrings based on a specified delimiter.
B. join: The join function is used to concatenate a list of strings into a single string with a specified delimiter.
C. slice: The slice function is used to extract a range of elements from a list or tuple.
D. chomp: The chomp function is not a valid string function in Terraform. It is not part of Terraform's standard function set for working with strings.
So, the correct answer is D. chomp.
ANSWER IS D. Chomp is not valid
Here are some examples of how to use these string functions in Terraform:
# Split a string into a list of strings, based on a comma delimiter
variable "tags" {
type = string
}
output "tags_list" {
value = split(var.tags, ",")
}
# Join a list of strings into a single string, using a space separator
variable "regions" {
type = list(string)
}
output "regions_string" {
value = join(var.regions, " ")
}
# Extract a substring from a string, starting at position 5 and ending at position 10
variable "hostname" {
type = string
}
output "hostname_suffix" {
value = slice(var.hostname, 5, 10)
}
that is not correct :
chomp removes newline characters at the end of a string.
This can be useful if, for example, the string was read from a file that has a newline character at the end.

chomp is not a valid string function in Terraform. The other three options are all valid string functions:
split splits a string into a list of strings, based on a delimiter.
join joins a list of strings into a single string, using a separator.
slice extracts a substring from a string, starting at a specified position and ending at a specified position or length.
that is not correct :
chomp removes newline characters at the end of a string.

The correct answer is C. Slice function is not listed in the official documentation of terraform string functions
https://developer.hashicorp.com/terraform/language/functions
slice is a collection function that extracts some consecutive elements from within a list.
