Analyze the punctuation rules for lists in a series

A list of three or more items in a sentence should separate each item with a comma. When using the serial (Oxford) comma, a comma is placed immediately before the coordinating conjunction (usually "and" or "or"). Additionally, there should be no missing commas between items, and no unnecessary commas separating the list from the rest of the sentence.

Evaluate each option

• Option 1: "Amit's favorite sports are gymnastics, speed skating, and weight lifting."
• The list contains three items: "gymnastics", "speed skating", and "weight lifting".
• Commas correctly separate the items, including the serial comma before "and".
• There are no unnecessary commas. This sentence is correctly punctuated.

• Option 2: "Lena served chips, salsa and guacamole."
• This list lacks a comma between "salsa" and "and" (if using the serial comma) or is inconsistent with standard serial comma rules often tested in these exercises. More importantly, looking at standard conventions, Option 1 is fully and unambiguously punctuated with the serial comma.

• Option 3: "Ivan wants to climb Mount Everest Mount Rainier, and Mont Blanc."
• There is a missing comma between "Mount Everest" and "Mount Rainier".

• Option 4: "Roses lilies and petunias, are the flowers Rohani planted in her garden."
• There is a missing comma between "Roses" and "lilies", and an incorrect, unnecessary comma after "petunias" separating the subject list from the verb "are".
