What does selection in algorithms mean?

Selection in algorithms refers to the process of evaluating conditions to choose a path of execution based on those conditions. This means that an algorithm can make decisions by determining whether certain criteria are met, allowing it to proceed in different directions. For instance, using conditional statements like "if" or "else" enables the algorithm to execute different blocks of code based on the truth value of a condition. This decision-making capability is crucial for handling various scenarios and inputs within an algorithm, guiding the flow of execution to produce the desired outcome.

The other options do not accurately represent the concept of selection in algorithms. Performing actions in a specific sequence refers to sequencing, which is about the order of operations. Assigning values to variables is an aspect of variable management and not selection. Looping through a dataset pertains to iteration, which involves repeating a process rather than making decisions based on conditions. Therefore, B correctly captures the essence of selection in algorithms.
