Answer:
A. They expect next year's one year yield to be roughly 2%
Explanation:
Since in the question it is mentioned that if the current one year, the yield of a zero-coupon bond is 4% and the current two years, the yield of a zero-coupon bond is 3% so for the one year it would be 2% approx as it reduced one percentage i.e 1% every one
Therefore in the given case, the correct option is A.
