The correct answer is: B. Insert
The insert() method allows you to insert a new character, substring, or list of characters at a specific position in a string.
The remove() method allows you to remove a character, substring, or list of characters from a string.
The import() method allows you to import a module into a Python script.
The delete() method allows you to delete a file from the filesystem.
Here is an example of how to use the insert() method:
“`python
string = “Hello, world!”
string.insert(5, “!”)
print(string)
Hello, world!!!
“`
In this example, the insert() method was used to insert the character ! at position 5 in the string "Hello, world!". The result is the string "Hello, world!!!".
