hi this question is from Knewton, can anyone help me with how to approach this?
Theoretically, water could remain in liquid form indefinitely in extremely low-energy environments, prevented from evaporating its molecules as a result of an insufficient level of kinetic energy present in the molecules on the liquid's surface.
(A) prevented from evaporating its molecules as a result of
(B) prevented from having its molecules evaporated by
(C) its molecules prevented from evaporating by

This is a simple sentence involving a subject (water) and a verb (could remain.) The second portion introduced by the prevented…. Is an appositive modifier defining the process of how water could remain in liquid form. Now let us go into the choices
(A) Prevented from evaporating its molecules because of --- 'prevented] from modifies water. This is wrong depiction. The phenomenon occurs only when the molecules are prevented and not water. In addition, this is just a natural event and there’s is no cause and effect to justify the use of as a result of.
(B) Prevented from having its molecules evaporated by --- modification error.
(C) its molecules prevented from evaporating by ; …. The noun molecules put the puzzle in place by plugging any possible mis-modification. It is not a run on as the second portion is not a clause. Prevented is simply a past participle. – Correct.
(D) its molecules prevented from being evaporated as a result of …. Use of being is unnecessary; as a result is wrong.
(E) Preventing its molecules from evaporating by … plainly wrong; means that water is preventing its molecules from evaporating.
