🆕 New Concept Discovered: Comma Usage Rules
How and when to use commas correctly

Step 1: Analyze the first option

The first option states: "To use instead of a coordinating conjunction in a compound sentence".

• Joining two independent clauses (complete thoughts) with only a comma and no coordinating conjunction (like and, but, or) creates a grammatical error known as a comma splice. Therefore, this is incorrect.

Step 2: Analyze the second option

The second option states: "To remove letters from words".

• The punctuation mark used to show omitted letters in contractions (such as turning "do not" into "don't") is an apostrophe, not a comma. Therefore, this is incorrect.

Step 3: Analyze the third option

The third option states: "To separate similar adjectives".

• In grammar, coordinate adjectives (similar adjectives that modify the same noun and can be reversed or joined by "and") must be separated by a comma (for example, "a warm, sunny day"). Therefore, this is a grammatically correct use of commas.

Answer:

To separate similar adjectives
