Conclusions:

I. Some gold are metals → False (As, there is no definite relation between gold and metal. Hence, false)

II. All metals are diamond → True (As, All metals are silver and All silver are diamond →  All metals are diamond)

III. Some silver are marble → False (As, there is no definite relation between silver and marble. Hence, false)

IV. All gold are marble → False (As, Some gold are marbles)

Hence, 'Only conclusion II follows'.
