Ansible provides several modules to manipulate the contents of files. The correct modules for changing the contents of a file are:

lineinfile: This module ensures a particular line is present or absent in a file, or it can replace existing lines that match a pattern.

replace: This module performs a search and replace on a string in a file.

patch: This module applies a patch to a file. It can be used to apply diffs to files, which essentially modifies the contents based on the diff provided.

The other options, insert and modify, are not standard Ansible modules for file content manipulation.
