D) Energy-efficient automobiles were first in demand during the mid-seventies, with the increased purchase continuing in them - Awkward construction
E) During the mid-seventies energy-efficient automobiles were in demand, and now the increased purchase of them has continued - - Awkward construction

You can knock out E based on redundant word "now", because "now" and "has" intend to mean that event is on going. Also, the second part ",and now the increased purchase of them has continued" is awkward.
