C. making possible
(答案→)D. made possible
解析：这题考查过去分词做定语：主句是“San Diego’s Zoo,Wild Animal Park,and Sea World are places”， “where residents and visitors alike can enjoy rare animals and plants in shows and exhibits”是定语从句。 “made possible in part by San Diego’s climate”这是过去分词短语做定语，修饰animals and plants相当于“which is made possible in part by San Diego’s climate”--这在一定程度上是圣地亚哥的气候造成的。选D。
