.htaccess allow directory listing?

Question

Apache HTTP Server

I create a .htaccess file in the right directory, I write the line Options Indexes
in it, I have 403 error , I
tried the "scientific poke method", comment the lines, but only RewriteEngine Off saves

here is my .htaccess from root

IndexIgnore *
Options +FollowSymlinks
Options -Indexes
RewriteEngine On
RewriteCond %{QUERY_STRING} base64_encode[^(]*\([^)]*\) [OR]
RewriteCond %{QUERY_STRING} (<|%3C)([^s]*s)+cript.*(>|%3E) [NC,OR]
RewriteCond %{QUERY_STRING} GLOBALS(=|\[|\%[0-9A-Z]{0,2}) [OR]
RewriteCond %{QUERY_STRING} _REQUEST(=|\[|\%[0-9A-Z]{0,2})
RewriteRule .* index.php [F]
RewriteRule .* - [E=HTTP_AUTHORIZATION:%{HTTP:Authorization}]
RewriteCond %{REQUEST_URI} !^/index\.php
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule .* index.php [L]
ErrorDocument 404 /404.html
ErrorDocument 403 /403.html

what's wrong there? why two rules?
RewriteRule .* index.php [F]
RewriteRule .* index.php [L]

everything turned out to be banal, simple - you just need to add +
for how much useful you learned
