Which three properties can be modified?

You are working with extended data types in Visual Studio.

You need to create an extension of an Extended Data Types (EDT) that is derived from base data types.

Which three properties can be modified? Each correct answer presents a complete solution. NOTE: Each correct selection is worth one point.
A . Label
B . String size
C . Alignment
D . IsExtensible
E . Form help

Answer: ABE

Explanation:

String size can be defined only on root EDTs. The system will use the largest value that is defined across the EDT and its extensions.

Labels and Help text properties can be changed by an extension, but only one value can remain.
