Machine code is written using ____
A
Binary/hexadecimal
B
English-like key words
C
Plain English
D
Abbreviated mnemonic keywords
Explanation: 

Detailed explanation-1: -Machine language is made up of instructions and data that are all binary numbers. Machine language is normally displayed in hexadecimal form so that it is a little bit easier to read.

Detailed explanation-2: -Hexadecimal is used extensively in assembly programming languages and in machine code. It is often used to refer to memory addresses. It can be used during the debugging stage of writing a computer program and to represent numbers stored in a CPU’s registers or in main memory.

Detailed explanation-3: -Binary information is sometimes also referred to as machine language since it represents the most fundamental level of information stored in a computer system. At a physical level, the 0s and 1s are stored in the central processing unit of a computer system using transistors.

Detailed explanation-4: -Machine code is a set of binary instructions consisting of 1’s and 0’s called bits. To the processor, 1 represents an electrical switch being on, while 0 means a switch is off. The 1’s and 0’s are grouped together in different ways, creating 8-bit combinations called bytes.

Detailed explanation-5: -The major difference between machine language and assembly language is that machine language is referred to as a binary language. It can be run on a computer directly. While an assembly language is a low-level programming language that must be converted into machine code using software called an assembler.
