A
A bundle of graphical images to be displayed by the program
B
Human-readable source code that describes a program
C
Low-level machine instructions that can be understood by a computer’s CPU.
D

Explanation: 

Detailed explanation-1: -Executable files contain binary machine code that has been compiled from source code. This low-level code instructs a computer’s central processing unit on how to run a program. The processor interprets the machine code and tells the computer’s hardware what to do.

Detailed explanation-2: -An executable file is a file that contains encoded instructions that can be executed by an operating system. Executable files can be platform specific (only executes in a Windows environment for example) or they can be cross platform (also executes on Unix/Linux, OSX and so on).

Detailed explanation-3: -A program (noun) is executable software that runs on a computer. It is similar to a script, but is often much larger in size and does not require a scripting engine to run. Instead, a program consists of compiled code that can run directly from the computer’s operating system.

Detailed explanation-4: -The executable file contains machine language instructions, or executable code, and is ready to run on the computer. These environments consist of a text editor, compiler, debugger, and other utilities integrated into a package with a single set of menus.
