I would say option 1 + corruption.

The outsourcing provider is corrupt as a whole or the ministry didnt pay the outsourcing provider well.

The ministry gets a lot of money for the projects and find the cheapest and corrupt outsourcing provider they could find out in the market so that they spend and also get the money back through backdoors.

But do note that the developers of the main booking site irctc.co.in may not be the same as the developers of indianrail.gov.in

Security and Usability has not been a major concern for the government websites. If you want the worst designed bus booking website then take a look here: http://www.tnstc.in/TNSTCOnline/
