An algorithm is a sequence of _________ instructionsQuestion 6Answera.overlappingb.unambiguousc.ambiguousd.legitimate

The correct answer to the question is b. unambiguous.

Explanation

An algorithm is fundamentally a well-defined set of steps or instructions designed to carry out a specific task or solve a problem. For an algorithm to be effective and reliable, it must be unambiguous, meaning that each instruction should be clear and precise, leaving no room for interpretation. This ensures that anyone or any machine following the algorithm will perform the task consistently and correctly.

In contrast:

• Overlapping (option a) suggests that instructions may conflict or interfere with each other, which is not desirable in an algorithm.
• Ambiguous (option c) means instructions could be interpreted in multiple ways, which could lead to different outcomes, thus rendering the algorithm ineffective.
• Legitimate (option d) could imply that the instructions are valid but does not specifically ensure clarity or precision.

Overall, the critical characteristic of an algorithm is its unambiguity, ensuring clear and explicit guidance through its sequence of instructions.
