  Answer:

  The major two B2B models are c. e-sourcing and sell-side marketplaces.

  Explanation:

  B2B is a business to business model which means the exchange of goods or services which happens between corporations or organizations but not with customers. It is providing services or goods online to other company. Example, a cyber-security firm providing online service to an e-commerce company as part of risk mitigation plan to avoid credit card fraud.

  The advantage of such model is sustainable and high-profit margin from repeated clients.

  One disadvantage is this model will be having a smaller number of customers.
