There is a real possibility that these animals could be frightened, ------a sudden loud noise.

A.being there
B.there was
C.there having been
D.should there be

D
应该是虚拟语气+倒装=if there should be
这些动物的确有可能受惊吓,如果突然有很响的声音的话.
相当于if there should be,这里should不是应该的意思,是假设 如:If you should change your mind, do let me know. 万一你要改变主意,一定要告诉我。
We should move to a larger house if we had the money.我们要是有钱就搬到大房子里去住.

选A.
doing可作伴随当时的情况来看.
一旦有突然的响声出现,动物确实可能受到惊吓.

D.should there be

虚拟语气,虚拟动词提前

D,是虚拟语气

B.there was

D
