I chose flat (absolute) 4%. It is just the reason being there was not convexity measure given.

And as you know... that duration is a linear measure (straight line) and convexity measure adjusts for the convexity of the curve. Without convexity given, we would not know where the increase or decrease would be greater or less than 4 %.

Moreover, I came across a similar question in the Schweser Q-Bank and the correct answer was an absolute number and not the greater or lesser than x number.

Hope this helps...
