All of the three reasons aimed at bringing more volume to Bitcoin specifically.
Dominance is likely to increase as people are losing faith from altcoins and the shift from altcoins to bitcoin will continue.
Second, China is a country with huge crypto volume. If as stated, crypto friendly regulations are expected in december, then yes, it will have a positive effect on the market. At least the speculation will take the price for an upward rally.
Third, Bakkt hasn't been able to make much a difference by now. That's why I don't much believe that launch of the option trading would make much a difference. But that in combination with Chinese news can help boost the price.
