Given this list of attributes:

-related to Business Delegate
-improves network performance
-can improve client performance through caching

Which design patten is being described?

A Transfer Object
B Service Locator
C Front Controller
D Intercepting Filter
E Model-View-Controller

Answer given is B

why can't it be answer A since Transfer Object reduces network traffic
can anyone explain which would be correct answer.

The right answer is B.
If you look at the description of Service Locator, you may note, that all of the attributes in the list are applicable to this pattern.
Transfer Object doesn't provide caching.

Please read
Service Locator and Business Delegate are releted.

Service Locator provides services to Business delegate in getting the access to remote objects.
