Question 7
Which programming languages can be managed, unmanaged, or both? (To answer, drag the appropriate option or options to the correct location or locations in the answer area. An option may be moved to more than one location, and some options may not be moved at all.)
Answer : 
Explanation:
Note:
*Managed code is a term coined by Microsoft to identify computer program source code that requires and will only execute under the management of a Common Language
Runtime virtual machine (resulting in bytecode).This applies to both C# and VB .Net.
Managed code needs a runtime (like the .NET CLT) to execute
*Microsoft's Visual C++ development environment can produce both managed code, running under the .NET CLR, or compiled binaries, running directly on the Windows platform with the help of its C++ Runtime Library.
