Are the underlined words in the sentence an independent clause, a subordinate clause, or neither?

My cousin visited me last weekend, and we talked until about two o'clock in the morning.

A.

subordinate clause

B.

independent clause

C.

neither

Since there are no words with underline, let me answer this question this way. There are two independent clauses in the sentence provided above: "My cousin visited me last weekend", and "we talked until about two o’clock in the morning." Therefore, the answer should be B. independent clause.
