Answer:
6.30%
Explanation:
For offering for the investor to prefer them to the corporate bond we need to calculate the after tax return which is shown below
After tax return is
= Before tax return × (1 - tax rate)
= 0.09 × (1 - 0.30)
= 0.063 or 6.30%
As the after tax return is 6.30% the same is to be offered for the investor
Hence, the correct answer is 6.30%
