In computer programming, what is a ‘loop’?
A
Something that is used to end a program
B
Something that is continually repeated until a certain condition is reached
C
Something that tells a program what to do
D
Something that is required to load a program
Explanation: 

Detailed explanation-1: -In computer programming, a loop is a sequence of instruction s that is continually repeated until a certain condition is reached. Typically, a certain process is done, such as getting an item of data and changing it, and then some condition is checked such as whether a counter has reached a prescribed number.

Detailed explanation-2: -A loop is a sequence of instructions that is repeated until a certain condition is met. An example would be the process of getting an item of data and changing it, and then making sure some condition is checked-such as if a counter has reached a prescribed number.

Detailed explanation-3: -The repeat / until loop is a loop that executes a block of statements repeatedly, until a given condition evaluates to true . The condition will be re-evaluated at the end of each iteration of the loop, allowing code inside the loop to affect the condition in order to terminate it.

Detailed explanation-4: -An infinite loop–sometimes called an endless loop–is a piece of code that lacks a functional exit so that it repeats indefinitely. In computer programming, a loop is a sequence of instructions that is continually repeated until a certain condition is reached.

Detailed explanation-5: -The while loop is used to repeat a section of code an unknown number of times until a specific condition is met.
