Taxation-zero coupon secured redeemable non-convertible deb

Hi All,

Greetings!

I hold some Zero Coupon Secured Redeemable Non-Convertible Debentures from Muthoot.

Could anyone let me know how do I show it in my Income Tax, whether I show it as Interest accrued or?

Thanks in advance

Details of the security are below
