Issue
As per this article "4. Disable Unnecessary Modules"
Ref: http://www.tecmint.com/apache-security-tips/
It’s always good to minor the chances of being a victim of any web attack. So it’s recommended to disable all those modules that are not in use currently. I disabled these modules mod_imap, mod_include, mod_info, mod_userdir, mod_autoindex.
After that httpd server is no restarting. Can you please help me to findout the issue.
I didn't get any errors on error_log or access_log
I got this following response if try to restart

Solution
You are answering your own question really:
Note what you said: " I disabled these modules mod_imap, mod_include, mod_info, mod_userdir, mod_autoindex."
And note the error you now have: "AH00526: Syntax error on line 16 of /etc/httpd/conf.d/autoindex.conf: Invalid command 'IndexOptions', perhaps misspelled or defined by a module not included in the server configuration".
You just have to remove the Option "IndexOptions", since it depends on mod_autoindex, which you have unloaded
When Apache complains about not knowing a directive or an option it means that either you misspelled it, or that the module that provides it is not being loaded.
