Answer options:

A.Business Account
B.Person Account
C.Group Account
D.Customer Account

Correct Answer: B 
Person Account provides a way to store information about individual people which is different than the business account that is used to store information about companies. 
Option A is incorrect because Business accounts are used to store information about companies. 
Options C and D are incorrect because Salesforce has two types of accounts person and business account. They don’t have any accounts called group account or customer account. You can always add a type field on your account to recognize customer account but when you create an account you have the option to create a person account if it`s enabled in your org or business account.
