2. My mother cooked delicious dishes. (independent clause)
3. This is the pen that I brought yesterday. (independent clause)
4. They did not come to my house. (independent clause)
Step-by-step explanation:
An independent clause is a group of words or clause that completes a thought and make a complete sentence without the need for any other words to make it complete. moreover, it can stand on its own as a full sentence.

The independent and dependent clauses in the given sentences are as follows-
1. Though he was sick (dependent clause), he attended the class. (independent clause)
2. My mother cooked delicious dishes. (independent clause)
3. This is the pen that I brought yesterday. (independent clause)
