[amp_mcq option1=”Different parts of the program executes physically” option2=”Different parts of the program executes sequentially” option3=”Different parts of the program executes conceptually” option4=”Different parts of the program executes sequentially and physically” correct=”option1″]
The correct answer is: A. Different parts of the program executes physically.
Concurrency is the ability of multiple tasks or threads to run simultaneously. This means that different parts of the program can be executed at the same time, even though they may be logically dependent on each other.
Option B is incorrect because it states that different parts of the program execute sequentially. This is not true, as concurrency allows different parts of the program to execute at the same time.
Option C is incorrect because it states that different parts of the program execute conceptually. This is not true, as concurrency requires different parts of the program to execute physically in order to be effective.
Option D is incorrect because it states that different parts of the program executes sequentially and physically. This is a combination of Option B and Option C, and it is also incorrect. Concurrency does not require different parts of the program to execute sequentially, and it does require different parts of the program to execute physically.
In conclusion, the correct answer is: A. Different parts of the program executes physically.
