A row of upright fan-shaped plates running down the spine provided the Stegosaurus dinosaur with an especially efficient solar heating and cooling system
to allow them to move comfortably through different climatic regions.
A)to allow them to move comfortably
B)to allow it a comfortable movement
C)that allowed it to move comfortably
D)that allowed their comfortable movement
E)Allowing them to move comfortably
In C and D the relative pronoun 'that' is supposed to modify both the heating and cooling systems and not just the cooling system. Mark the words 'different climatic regions' in the non-underlined portion. It is an integral, two - in - one system that heats in the cold climate and cools in the hot season. That is how the animal was able to move comfortably in different climates.
we may refer to an
OG question regarding the relative pronoun modification.
