Which is the best plugin for adding contact forms in wordpress site??
You can try using 'contact form 7', its pretty good.
WPForms' drag & drop online form builder makes it the most user-friendly form plugin for WordPress. WPForms Lite is available for free in the official WordPress plugin directory meaning you can install it on as many sites as you like for free.
Contact form7 or disqus are the best options.
