Answers:

785) .OA - C - idiomatic - forbid X to Y

786). (OG 10th Ques No. 96) - OA - E - with its idiomatic and precise noun clause, is the best answer
OE: The correct choice will include to assure, an infinitive parallel to to prevent. Thus, A, B, and C are disqualified.
A, C - incorrect - the participial phrases in A and C (assuring... ), easily construed as adjectives modifying latches, are confusing.
B, C - incorrect - in omitting the noun doors, they fail both to specify what is being closed and to supply an antecedent for the pronoun them.
D - incorrect - offers the necessary infinitive, but the gerund phrase closing ... imprecisely refers to the act of closing the doors rather than to the condition of the closed doors.
