A bar code is a series of bars and spaces representing numbers or letters.
<h3><u>
Explanation:</u></h3>
A method that is used for the purpose of representing a data in the form of a picture or image that can be easily understood by the machine. It consists of many lines that has different widths and spaces. They either represent the letter or a number. These are mainly used for the representation of data in the machine understandable format.
For example an UPC-A bar codes has 12 numbers. The numbering system is represented by the first digit. The manufacturer will be represented by the next five digits in it. The product will be represented by the five digits following it. Check digit is represented in the last digit.

Answer:
The answer is "The program can also be expressed as a binary code, but it is easier for people to understand when it is expressed in a higher programming language".
Explanation:
In the given question some details are missing that is options of the question that can be given as follows:
A. The program can also be expressed as a binary code, but it is easier for people to understand when it is expressed in a higher programming language.
B. The program can also be represented as a binary code that reduces the likelihood of errors.
C. Binary code can not be used for binary code, because binary code can only represent data.
D. Some parts of the program, however, should be printed in a higher-level language for the operation.
The computer knows the only binary language, It is a form of 0 and 1, but this language can't be understood by the user. It will convert into high-level language, that is understood by the user, that's why this option is correct. In which accepts of option A, all options are wrong that can be described as follows:
- In option B, It is wrong, because the user may not understand binary language, and he can also be writing some wrong code that is converted in binary code, that will increase error.
- In option C and option D, is incorrect because all the data that is stored in the computer is in the form of binary code.
