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.
This can be useful if, for example, the string was read from a file that has a newline character at the end.

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.

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.

If you are interested to learn about the Terraform string functions you can visit the following link https://bitsto.cloud/terraform-string-functions/
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.
