Another model that allows two software components to communicate

with each other independent of their platforms operating systems and
languages of implementation is:

A.
Basic Object Model (BOM)

B.
Sandbox

C.
Common Object Model (COM)

D.
Spiral Model

Explanation:
As in the object-oriented paradigm, COM works with encapsulated
objects. Communications with a COM object are through an
interface contract between an object and its clients that defines the
functions that are available in the object and the behavior of the
object when the functions are calleD.
*Answer a sandbox, is an access
control-based protection mechanism. It is commonly applied to
restrict the access rights of mobile code that is downloaded from a
Web site as an applet. The code is set up to run in a sandbox that
blocks its access to the local workstations hard disk, thus preventing
the code from malicious activity. The sandbox is usually interpreted
by a virtual machine such as the Java Virtual MachinE.
*Answer BOM is a distracter.
* Spiral Model refers to the software development life cycle.
