End user has to remove special characters in staff id column and check whether VLOOKUP gives error.
Answer:
Option d is the correct answer.
Explanation:
Machine language is a language that is understood by any machine because it is made from the electric signal which has only two states on and off. On state refers to 1 and off-state refers to 1. The computer is also a type of machine so it can also understand machine language. The above question asked about the instruction which is made by 0's and 1's and it is used for the computers then the answer is Machine language which is described above and which is stated from the option d. Hence option d is the correct answer while the other is not because--
- Option 'a' states about COBOL language which is an example of high-level-language, not the example of machine language.
- Option b states about the programming language which is a mixture of all language of computers.
- Option c states about ASCII which is not the correct answer.
