Answer:
The correct option is D, eight months for the first payment; six months for the second payment
Step-by-step explanation:
From the information provided,it is very clear that interest payment would not made until January 1st 2021,which is 8 months after the date of bond issue.
This means that interest due on July 1st 2020 of two months would be paid together with that which becomes due on 1st January 2021 for six months,hence the first interest payment is for 8 months while the next one would the normal six-month cycle.
As a result,it is convincing enough that option D fits the explanation in all respects.
