Fixed Income Reading 61

EOC No. 6, Page 344 Isn’t statement B correct? The sinking fund provision is applicable from 2010 to 2019, not in the first five years. But the explanation says that if the sinking fund provision is used, investor will get only par value. Am I missing something?

This is totally from memory so could be completely off, but I seem to remember getting confused by that question too…is there something about an accelerated sinking fund provision too, which covers the whole time period? That could explain it… Will have a look at the question when I get home.
