Dear Neelu, you should ideally give Mother's and Father's name as per Class 10 certificate. However once you fill in all the details it gives you a 'Review' option. You can review the information and press 'Back' button' in case you need to make some changes. However if you have missed that option I would suggest you to reach out to their helpline no# at 1800118002 from 9.30 am to 5.30 pm. Unfortunately this cannot be changed in the correction window as it doesn't effect the merit list. So it's a good option that you take their advice on this.
