During the winter months, the park transforms into a snowy wonderland. Many families enjoy skiing, snowboarding, and ice skating.
- NO CHANGE (correct answer)
- and, ice
- and ice,
- and, ice,
Explanation: This question tests the use of commas in a series (list of three or more items). The sentence lists three winter activities: "skiing, snowboarding, and ice skating." The original text correctly omits commas around "and ice" because "ice" is part of the compound term "ice skating," not a separate item in the series. The comma after "snowboarding" is the serial comma before the final item "ice skating." Choice B incorrectly adds a comma after "and," which would separate the coordinating conjunction from its object. Choice C incorrectly adds a comma after "ice," creating an ungrammatical separation within the compound term. Choice D combines both errors. When items in a series contain compound terms, avoid inserting commas within those terms.
