Consider Two Demand Curves and the Same Price Change for Both

Consider two demand curves and the same price change for both. If the resulting percentage change in quantity demanded is greater for one (D1) than the other (D2) , we can conclude

A) that D1 is elastic and D2 is inelastic.
B) that D2 is more elastic than D1.
C) that D1 is inelastic and D2 is elastic.
D) that D1 is more elastic than D2.
E) nothing about their relative elasticities.
