Solution

Accordingly the answer is B(Logical).

ADT is expanded as Abstract Data Type.

ADT is defined as class of objects whose logical behaviour is defined by set of values and set of operations.

ADT\'s are used in the desing and analysis of alogrithms, data structures, and software systems which inturn don not correspond some specific components of computer languages.

At the logical level we formally define our stack ADT using a java interface.
