Answer:
A.
Both A few of the new sports channels are worth watching and many of them carry obscure games are independent clauses joined by the coordinating conjunction but.
Step-by-step explanation:
An independent clause has a subject and a verb. It is a complete idea and can be read by itself. The first independent clause is "A few of the new sports channels are worth watching". The subject is "few" and the verb is "are". This clause is a complete idea by itself. The second independent clause is "many of them carry obscure games". The subject of this clause is "many" and the verb is "carry". It is also a complete idea by itself.
