Paypal Commerce - Question About Multisellers On One Cart

Hello,
I have questions about a few scenarios on Paypal Commerce integration with my multivendor plus. It states on the cscart user guide. "Vendors connect their PayPal business accounts to receive the money for their products that have been sold. If a customer adds products from different vendors to his cart, and all those vendors have their PayPal accounts connected to the marketplace, then this payment method will be offered to the customer."
Please assist by answering my questions below:
Scenario 1:
If a buyer add to his cart products from multiple sellers, ie.
SellerA is setup to receive payments via Stripe only
SellerB is setup to receive payments via Paypal only
Then what payment method would appear for the buyer on checkout?
Scenario 2:
If a buyer add to his cart products from multiple sellers, ie.
SellerA is setup to receive payments via Stripe only
SellerB is setup to receive payments via Paypal only
SellerC is setup to receive payments via both
Then what payment method would appear for the buyer on checkout?
