Answer is B.

I think you are confused with Present participle and past participle.

Present participle = Verbing.
Past participle = third form of verb.

Present participle:

COMMA + VERBING: Modifies the entire preceding clause, and the verbing retains the subject of a verb.

They have helped the poor, giving food and cloths.

PAST PARTICIPLE: On the other hand, past participle is a NOUN modifier. It modifies NOUN near to it.

Built in 1990, the building looks nice.

The building, built in 1990, looks nice.

--> In both the case "past participle"-built-modifies the building.

Now, come to the question:

"Equipped with ..." modifies the nearest NOUN "MP3 players".
